Journal of Cleaner Production, 452, 2024年05月01日
Recent research on the influence of four types of alkanolamines on the hydration of cementitious systems is summarized. In OPC, alkanolamines primarily affect aluminate hydration, as demonstrated by the chelation effects of various metal ions on alite hydration. The dosage and stability constants of chelation play important roles in this process. The effect of alkanolamines in blended cement was reviewed, and the enhancement was attributed to the directly enhanced dissolution of supplementary cementitious materials and enhanced pozzolanic reaction. The effects of alkanolamines can be further improved by interactions with other admixtures with appropriate mix designs in various cementitious systems. - 回転式加熱炉を用いたアルカリ長石による飛灰中セシウムの難溶性態化率向上

日本語, 現在,除染廃棄物等の減容化熱処理が行われている.減容化熱処理では,セシウム(Cs)を揮発分離することからCsが濃縮した飛灰が発生する.塩化揮発により生成する飛灰中のCsは主に塩化物であるため易溶性である.最終処分に向けてCsは難溶性であることが望ましい.本研究では,アルカリ長石が加熱条件下でCsを難溶性態化する現象を用いて,回転式加熱炉により飛灰中Csの難溶性態化率向上が可能かを検討した.インド長石,焼却飛灰,CsClを混合し,回転式加熱炉で700℃で加熱した.回転数4rpm,700℃の条件で15時間加熱した結果,添加したCsの99%が難溶性態化した.インド長石の添加割合を飛灰1に対して0.8程度に減らしても加熱時間15時間で難溶性態化率96%を達成した. - 重曹の真空加熱によるごみ焼却排ガス処理用の多孔質炭酸ナトリウムの製造

英語, 研究論文(学術雑誌), This study was conducted to evaluate the composting processes in Sri Lanka and to identify essential improvements. The study consisted of a questionnaire survey, field observations, and interviews. The main shortcomings identified by this study were: no source separation at origin, and no monitoring for temperature, moisture, stability, or maturity during processes of composting. These problems hinder the smooth operation of the composting processes and lead to low demand for compost. Based on the findings, the recommendations for increasing the demand for compost are performing source separation during waste collections, improvement of processes by monitoring the temperature and moisture, and marketing compost so as to improve the popularity of the compost among farmers. - Removal and speciation of mercury compounds in flue gas from a waste incinerator

英語, 研究論文(学術雑誌), The management and control of mercury emissions from waste incinerators have become more significant, because waste incinerators are sinks to treat mercury-containing consumer products. This study investigated the effects of mercury concentrations and waste incineration temperatures on mercury speciation using a lab-scale experimental instrument. The removal characteristics of different mercury species were also investigated using an apparatus to simulate the fabric filter with a thin layer of additives such as Ca(OH)(2) and NaHCO3, activated carbon (AC), and fly ash. HgCl2 generation rates peaked at 800 degrees C for initial Hg-0 concentrations of 0.08-3.61mg/Nm(3) in the presence of 400ppm HCl. A linear relationship was established between the generation rate of HgCl2 and the logarithmic value of initial mercury concentration. Fly ash proved highly efficient in mercury removal, being equal or superior to AC. On the other hand, Ca(OH)(2) and NaHCO3 were shown to have no effects on mercury removal. In the dry-scrubbing process, alkali agent is often sprayed in amounts beyond those stoichiometrically required to aid acidic gas removal. The research suggests, however, that this may hinder mercury removal from the flue gas of solid waste incinerators. - Effects of phosphoric acid sprayed into an incinerator furnace on the flue gas pressure drop at fabric filters

英語, 研究論文(学術雑誌), Fabric filters are widely used to remove dust from flue gas generated by waste incineration. However, a pressure drop occurs at the filters, caused by growth of a dust layer on the filter fabric despite regular cleaning by pulsed-jet air. The pressure drop at the fabric filters leads to energy consumption at induced draft fan to keep the incinerator on negative pressure, so that its proper control is important to operate incineration facility efficiently. The pressure drop at fabric filters decreased whenever phosphoric acid wastewater (PAW) was sprayed into an incinerator for treating industrial waste. Operational data obtained from the incineration facility were analyzed to determine the short- and long-term effects of PAW spraying on the pressure drop. For the short-term effect, it was confirmed that the pressure drop at the fabric filters always decreased to 0.3-1.2 kPa within about 5 h after spraying PAW. This effect was expected to be obtained by about one third of present PAW spraying amount. However, from the long-term perspective, the pressure drop showed an increase in the periods of PAW spraying compared with periods for which PAW spraying was not performed. The pressure drop increase was particularly noticeable after the initial PAW spraying, regardless of the age and type of fabric filters used. These results suggest that present PAW spraying causes a temporary pressure drop reduction, leading to short-term energy consumption savings; however, it also causes an increase of the pressure drop over the long-term, degrading the overall operating conditions. Thus, appropriate PAW spraying conditions are needed to make effective use of PAW to reduce the pressure drop at fabric filters from a short- and long-term point of view. (C) 2016 Elsevier Ltd.

英語, 研究論文(学術雑誌), Scallop entrails are organic wastes containing abundant proteins and minerals but are considered difficult to recycle because of high cadmium concentrations. In this work, the current problem of scallop entrails recycling was investigated and a subcritical hydrothermal treatment (SCHT) was examined for the recovery of liquid fertilizer from scallop entrails. Scallop entrails are mainly recycled for composting and feedstuff production. However, the dilution by mixing scallop entrails with other feed waste was the sole countermeasure to reduce the cadmium concentration of compost. For feedstuff production, whole product derived from scallop entrails was exported to other countries instead of domestic utilization. Temperature, retention time (RT) at given temperature, and liquid-to-solid (LS) ratio were examined as SCHT conditions for scallop entrails processing. The extraction ratio of each constituent mainly depends on the temperature rather than the RT or the LS ratio. Upon the SCHT of scallop entrails at 200 degrees C, an RT of 20min, and an LS ratio of 10, the extraction of fertilizer constituents such as nitrogen, phosphorus, and potassium from the liquid product was optimum, whereas the release of cadmium was suppressed. The concentrations of heavy metals in the liquid product obtained using the above-mentioned SCHT conditions were below the maximum permissible concentration stipulated by the Fertilizer Control Law. SCHT is considered to be a feasible recycling method for scallop entrails to recover fertilizer components with a concomitant separation of cadmium from the product. - Characterization of products obtained from pyrolysis and steam gasification of wood waste, RDF, and RPF

英語, 研究論文(学術雑誌), Pyrolysis and steam gasification of woody biomass chip (WBC) obtained from construction and demolition wastes, refuse-derived fuel (RDF), and refuse paper and plastic fuel (RPF) were performed at various temperatures using a lab-scale instrument. The gas, liquid, and solid products were examined to determine their generation amounts, properties, and the carbon balance between raw material and products.
The amount of product gas and its hydrogen concentration showed a considerable difference depending on pyrolysis and steam gasification at higher temperature. The reaction of steam and solid product, char, contributed to an increase in gas amount and hydrogen concentration. The amount of liquid products generated greatly depended on temperature rather than pyrolysis or steam gasification. The compositions of liquid product varied relying on raw materials used at 500 degrees C but the polycyclic aromatic hydrocarbons became the major compounds at 900 degrees C irrespective of the raw materials used. Almost fixed carbon (FC) of raw materials remained as solid products under pyrolysis condition whereas FC started to decompose at 700 degrees C under steam gasification condition.
For WBC, both char utilization by pyrolysis at low temperature (500 degrees C) and syngas recovery by steam gasification at higher temperature (900 degrees C) might be practical options. From the results of carbon balance of RDF and RPF, it was confirmed that the carbon conversion to liquid products conspicuously increased as the amount of plastic increased in the raw material. To recover feedstock from RPF, pyrolysis for oil recovery at low temperature (500 degrees C) might be one of viable options. Steam gasification at 900 degrees C could be an option but the method of tar reforming (e.g. catalyst utilization) should be considered. (C) 2013 Elsevier Ltd.

英語, 研究論文(学術雑誌), High-temperature particle control (HTPC) using a ceramic filter is a dust collection method without inefficient cooling and reheating of flue gas treatment; thus, its use is expected to improve the energy recovery efficiency of municipal solid waste incinerators (MSWIs). However, there are concerns regarding de novo synthesis and a decrease in the adsorptive removal efficiency of dioxins (DXNs) at approximately 300 degrees C. In this study, the effect of natural and activated acid clays on the decomposition of monochlorobenzene (MCB), one of the organochlorine compounds in MSW flue gas, was investigated. From the results of MCB removal tests at 30-300 degrees C, the clays were classified as adsorption, decomposition, and low removal types. More than half of the clays (four kinds of natural acid clays and two kinds of activated acid clays) were of the decomposition type. In addition, the presence of Cl atoms detached from MCB was confirmed by washing the clay used in the MCB removal test at 300 degrees C. Activated acid clay was expected to have high dechlorination performance because of its proton-rich-composition, but only two clays were classed as decomposition type. Conversely, all the natural acid clays used in this work were of the decomposition type, which contained relatively higher di- and trivalent metal oxides such as Al2O3, Fe2O3, MgO, and CaO. These metal oxides might contribute to the catalytic dechlorination of MCB at 300 degrees C. Therefore, natural and activated acid clays can be used as alternatives for activated carbon at 300 degrees C to remove organochloride compounds such as DXNs. Their utilization is expected to mitigate the latent risks related to the adoption of HTPC, and also to contribute to the improvement of energy recovery efficiency of MSWI.
Implications: The effect of natural and activated acid clays on MCB decomposition was investigated to evaluate their suitability as materials for the removal of organochlorine compounds, such as DXNs, from MSWI flue gas at approximately 300 degrees C. More than half of the clays used in this study showed the decomposition characteristics of MCB. The presence of Cl atoms in the clay used in the MCB removal test at 300 degrees C proved the occurrence of MCB decomposition. The results of this study suggest a novel flue gas treatment method to establish high-energy efficient MSWI systems. - Recovery of solid fuel from municipal solid waste by hydrothermal treatment using subcritical water

英語, 研究論文(学術雑誌), Hydrothermal treatments using subcritical water (HTSW) such as that at 234 degrees C and 3 MPa (LT condition) and 295 C and 8 MPa (HT condition) were investigated to recover solid fuel from municipal solid waste (MSW). Printing paper, dog food (DF), wooden chopsticks, and mixed plastic film and sheets of polyethylene, polypropylene, and polystyrene were prepared as model MSW components, in which polyvinylchloride (PVC) powder and sodium chloride were used to simulate Cl sources.
While more than 75% of carbon in paper. OF, and wood was recovered as char under both LT and HT conditions, plastics did not degrade under either IT or HT conditions. The heating value (HV) of obtained char was 13,886-27,544 kJ/kg and was comparable to that of brown coal and lignite. Higher formation of fixed carbon and greater oxygen dissociation during HTSW were thought to improve the HV of char.
Cl atoms added as PVC powder and sodium chloride to raw material remained in char after HTSW. However, most Cl originating from PVC was found to converse into soluble Cl compounds during HTSW under the HT condition and could be removed by washing.
From these results, the merit of HTSW as a method of recovering solid fuel from MSW is considered to produce char with minimal carbon loss without a drying process prior to HTSW. In addition, Cl originating from PVC decomposes into soluble Cl compound under the HT condition. The combination of HTSW under the HT condition and char washing might improve the quality of char as alternative fuel. (C) 2011 Elsevier Ltd.

英語, Scallop entrails include a lot of nutrient such as nitrogen, phosphorus, and potassium, which contain toxic heavy metal such as cadmium in digestive gland. In this work, the current situation of scallop entrails recycling was investigated. Besides, hydrothermal treatment using subcritical water (HTSW) was examined as a recovery method of liquid fertilizer from scallop entrails. 59 wt% of scallop entrails was recycled by composting and 34 wt% of that was recycled by feedstuff manufacturing respectively. In composting facilities, scallop entrails have been commonly mixed with other input wastes to adjust cadmium concentration of compost under 5 mg/kg. Some facilities have proven to be suffered from lack of input waste to mix with scallop entrails in some case. On the other hand, at the HTSW of scallop entrails and digestive gland in the condition of 200oC, RT=20 min, and L/S ratio=10, the extraction of fertilizer components such as nitrogen, phosphorus, and potassium to liquid product was maximized whereas the release of cadmium tended to be suppressed. The concentrations of heavy metals were lower than maximum permissible concentration of Fertilizer Regulation Act. From these results, HTSW was considered as one of feasible recycling methods for scallop entrails with separating cadmium from product. - 活性白土を用いたごみ焼却排ガス中クロロベンゼンの脱塩素効果に関する研究

ごみ焼却施設では、排ガス中のばいじん、酸性ガス、重金属、ダイオキシン類などの排出低減のため、様々な処理プロセスが採用されている。近年、排ガス処理システムにおいて環境汚染物質の排出抑制とともにエネルギー・コスト面での効率化が求められ、各プロセスの見直しや新たな技術開発が行われている。そのうち、セラミックフィルターを用いた高温集塵方式は、排ガス減温や再加熱などのプロセスの省略が可能となり、施設全体のエネルギー・コスト削減効果が期待されている。本研究では、集塵操作温度である300℃において、活性炭に代わる無機材料として活性白土を用いた脱塩素化によるダイオキシン類の分解可能性を検討する。その基礎研究として、国内で生産される活性白土を用い、温度条件によるクロロベンゼンの除去率と除去特性、脱塩素効果について確認した。その結果、活性白土には脱塩素効果をもつものとそうではないものがあることが判明した。 - Survey of carbonization facilities for municipal solid waste treatment in Japan

英語, 研究論文(学術雑誌), The operations of carbonization facilities for municipal solid waste treatment in Japan were examined. Input waste, system processes, material flows, quality of char and its utilization, fuel and chemical consumption, control of facility emissions, and trouble areas in facility operation were investigated and analyzed. Although carbonization is a technically available thermochemical conversion method for municipal solid waste treatment, problems of energy efficiency and char utilization must be solved for carbonization to be competitive. Possible solutions include (1) optimizing the composition of input waste, treatment scale, organization of unit processes, operational methods, and quality and yield of char on the basis of analysis and feedback of long-term operating data of present operating facilities and (2) securing stable char demands by linking with local industries such as thermal electric power companies, iron manufacturing plants, and cement production plants.

英語, 研究論文(学術雑誌), The selective non-catalytic reduction (SNCR) process is one of the methods used to reduce NO(x) to N(2) and H(2)O by injecting NH(3) or urea solution into a high-temperature furnace. Merits of this method include simple handling, low cost, and energy savings, However, a critical problem of the SNCR process is the generation of ammonia slip; in reactions with HCl in flue gas, ammonium chloride is generated and forms detached white plumes near the stack, Using a laboratory-scale experimental apparatus, we examined the possibility of NH(4)Cl collection and removal by a bag filter (BF). The molar NH(3)/HCl ratio of the compound collected at the filter was nearly one, regardless of gas temperature, retention time, and concentration, confirming the formation of NH(4)Cl. The NH(4)Cl generation ratio increased as reaction temperature decreased, indicating that the collection efficiency of NH(4)Cl should increase if the BF is operated at the lowest possible temperature while avoiding the critical point causing low-temperature corrosion (e.g., 150 C). In addition, the use of activated carbon injection in the front of the BF and the dust layer on the BF are expected to capture slipped ammonia at the BF and reduce NH(4)Cl fume generation in the stack.

英語, 研究論文(学術雑誌), Automobile shredder residue (ASR) was pretreated to improve its quality for fuel utilization. Composition analysis revealed that ASR components could be classified into four groups: (1) urethane and textile-light fraction and combustibles containing low levels of ash and Cl; (2) plastics and rubber-light or heavy fraction and combustibles containing high levels of Cl; (3) metals and electrical wire-heavy fraction and incombustibles, and (4) particles smaller titan 5.6 mm with high ash contents. Based on these results, we successively performed sieving to remove particles smaller than 5.6 mm, float and sink separations to reject the heavy fraction and plastics and rubber containing Cl, thermal treatment under an inert atmosphere to remove Cl derived from PVC, and char washing to remove soluble chlorides. This series of pretreatments enabled the removal of 78% of the ash and 91% of the Cl from ASR. Sieving using a 5.6-mm mesh removed a considerable amount of ash. Product quality was markedly improved after the float and sink method. Specifically, the sink process using a 1.1 g cm(-3) medium fluid rejected almost all rubber containing Cl and a large amount of PVC. The remaining Cl in char, after heating at 300 degrees C under an inert atmosphere and washing, was considered to be present as insoluble chlorides that volatilized at temperatures above 300 degrees C. Based on a tradeoff relationship between product quality and treatment cost, ASR may be utilized as a form of refuse plastic fuel or char. (C) 2007 Elsevier Ltd.

英語, 研究論文(学術雑誌), To evaluate carbonization as a thermal pretreatment method for landfilling, the releasing characteristics of organic and inorganic constituents from carbonization residue derived from shredded residue of bulky waste was investigated by means of batch and column leaching tests. Shredded residue of bulky waste itself and its incineration ash were tested together to compare pretreatment methods.
In batch leaching tests at a liquid/solid ratio of 10, the release of organic carbon from carbonization residue was at a remarkably low level. Besides, carbonization contributed to immobilize heavy metals such as chromium, cadmium, and lead within its residue.
In column tests, the discharges of organic constituents were lowest from carbonization residue under aerobic conditions due to microbial activity. The leaching of Cd, Cr, Pb, and Cu from carbonization residue was suppressed under anaerobic conditions; however, this suppression effect tended to be weaker under aerobic conditions.
From the results showing that the total releasing amounts of organic and inorganic constituents from carbonization residue are so low as to be comparable to that of incineration ash, carbonization can be considered as one of the thermal pretreatment methods of organic wastes.

英語, 研究論文(学術雑誌), This study characterized and removed ash from waste-derived char to improve the quality of char as fuel. Municipal solid waste (MSW) and automobile shredder residue (ASR) were carbonized at 450 degrees C and at 500 degrees C, respectively, in a rotary kiln with a nitrogen atmosphere for I h. MSW and ASR char were subjected to sieving and pulverization-sieving to screen incombustibles and the ash-rich fraction, after which float-sink separation, froth floatation, and oil agglomeration were applied to remove ash from the char. The established target quality was (1) less than 30% ash content and (2) more than 20,000 kJ/kg heating value. However, the rate of combustibles recovery had to be lowered to produce a good quality of char along with a high heating value. MSW char attained the targeted quality level using froth floatation or oil agglomeration, whereas, neither separation method was able to make ASR-derived char satisfy the target.
Based on the assumption that particle properties of char are determined by the weight ratio of combustibles and ash, the densities of combustibles and ash in char were estimated using the results of float-sink separation, X-ray diffraction (XRD) analysis, and elemental content. To verify the above assumption, an energy dispersive X-ray/scanning electron microscope (EDX/SEM) analyzer was used to observe char particles. (c) 2007 Elsevier Ltd.

英語, 研究論文(学術雑誌), The pyrolysis residue (SP) of sewage sludge (SS) produced at 500 OC was subjected to batch and column leaching tests to investigate the release of its organic and inorganic constituents and metals. For comparison, incineration ash (SI) obtained from a SS incinerator was also tested. Pyrolysis and incineration reduced organic matter of SS from 0.78 kg kg(-1) -dry SS to 0.16 and 0.01 kg kg(-1) -dry SS, respectively. Heavy metals remained in SP without being volatilized, although Cd and Pb were transferred into the off-gas during incineration.
In the batch leaching test with the leaching liquid-to-solid mass ratio (L/S) = 10, the pH of the SS, SP, and SI filtrates was 6.3, 7.9, and 11.0, respectively. The total organic carbon concentrations were in the order SS (877 1 mg 1-1) >> SP (99 mg 1(-1)) > SI (26 mg 1(-1)). The SP and Sl filtrates met the landfill standard for the Cd and Pb concentrations (<0.3 mg 1(-1)), In the column tests, although the SP contained more organic matter than that of SI, its carbon discharge into the leachate under aerobic conditions was similar to that of SI under anaerobic conditions. The leaching of heavy metals, such as Cd, Cr, Pb, and Zn, was also suppressed in SP during the active decomposition of organic matter.
We demonstrated that pyrolysis reduces the potential release of pollutants from sewage sludge in landfill, making it a promising method of treating sewage sludge before landfilling.

英語, 研究論文(学術雑誌), Carbonization is a kind of pyrolysis process to produce char from organic materials under an inert atmosphere. In this work chars derived from various solid wastes were characterized from the standpoint of fuel recovery and pretreatment of waste before landfilling. Sixteen kinds of municipal and industrial solid wastes such as residential combustible wastes, non-combustible wastes, bulky wastes, construction and demolition wastes, auto shredder residue, and sludges were carbonized at 500 C for 1 h under nitrogen atmosphere.
In order to evaluate the quality of char as fuel, proximate analysis and heating value were examined. The composition of raw waste had a significant influence on the quality of produced char. The higher the ratio of woody biomass in waste, the higher heating value of char produced. Moreover, an equation to estimate heating value of char was developed by using the weight fraction of fixed carbon and volatile matter in char.
De-ashing and chlorine :removal were performed to improve the quality of char. The pulverization and sieving method seems to be effective for separation of incombustibles such as metal rather than ash. Most char met a 0.5 wt% chlorine criterion for utilization as fuel in a shaft blast furnace after it was subjected to repeated water-washing.
Carbonization could remove a considerable amount of organic matter from raw waste. In addition, the leaching of heavy metals such as chrome, cadmium, and lead appears to be significantly suppressed by carbonization regardless of the type of raw waste. From these results, carbonization could be considered as a pretreatment method for waste before landfilling, as well as for fuel recovery. (c) 2006 Elsevier Ltd.

英語, 研究論文(学術雑誌), Chlorine in char derived from municipal solid waste (MSW) was characterized and quantified based on its water solubility: easily water-soluble, hardly water-soluble, and non-water-soluble chlorine. For that, a four-cycle process of water-washing, heating or carbonation were carried out. In order to confirm the characteristics of non-water-soluble chlorine, additional thermal treatment and an alkali-acid washing process were applied to washed char. It was found that a large particle size of char (0.5-1.0 mm) significantly contributed to the amount of non-water-soluble chlorine. Pulverization and HNO3-HF digestion were performed to identify a factor to interfere chlorine release from char with a large particle size. Pulverization was proven ineffective for release of non-water-soluble chlorine, whereas approximately 32% of non-water-soluble chlorine was extracted by HNO3-HF digestion. Therefore, the presence of non-water-soluble chlorine is likely to originate from its chemical property rather than simply from its physical one. (c) 2005 Elsevier Ltd.

英語, 研究論文(学術雑誌), This research was designed to develop a separation method for partially overlapped peaks on derivative thermogravimetry (DTG) curves and to apply this technique to estimate the dehydrochlorination kinetics of PVC (Polyvinyl Chloride). It was assumed that two peaks might be responsible for the independent dehydrochlorination reactions of two PVC compounds. Dehydrochlorination kinetics of PVC were investigated using a thermogravimetric analysis (TGA) system at heating rates of 0.75, 1, and 1.25 K/min under a nitrogen atmosphere. A key hypothesis for applying the separation method was that, under dynamic operations, there would be a unique temperature region in which each compound would decompose uniquely. Firstly, the apparent kinetic parameters and initial mass of the thermally-more-stable PVC compound were estimated from the partial DTG curve in the range where only this compound might decompose. Then, the dehydrochlorination kinetics of the thermally-less-stable PVC compound were elucidated by analyzing its TGA curve that was derived by subtracting the TGA curve of the more-stable PVC compound from the original curve. It is essential to separate the overlapped peaks on the DTG curves to accurately interpret the kinetics of the independent reactions. This separation technique can be applied to analyze the kinetic parameters of two independent reactions provided that there are unique temperature regions in which each compound decomposes solely. - Pyrolysis Kinetics of Agricultural Plastic Film

竪型ストーカ式焼却炉は,従来のストーカ式炉に比べごみ層の横方向に燃えむらがなく,より均質で高発熱量の可燃ガスを発生させ,効率の良い燃焼が実現できる。今後のごみ焼却において活用が期待される新たな燃焼装置であるが,まだ運転実績が少なく,その特徴が知られていない。本研究では,排ガス中のNOX低減の観点からごみ層の還元雰囲気下でNOXの自己脱硝反応に着目し,竪型ストーカ式炉焼却炉におけるごみ層でのNOX,HCN,NH3の発生特性と燃焼室での酸素濃度,温度,共存可燃ガス類等がHCN,NH3の酸化・還元挙動に及ぼす影響等について実炉での排ガス濃度測定,室内実験,燃焼シミュレーションを通じて明らかにした。
