    Our previous experimental study showed that Na+-exchanged coal prepared from low-cost natural soda ash is an excellent catalyst for steam gasification of low-rank coals using fixed-bed quartz reactors. However, it is difficult to experimentally clarify the effect of Na ion exchange on low-rank coal. In order to investigate the influence of Na+ ions on low-rank coal, this study determined the electronic state between the Na+-exchanged coal model and raw coal model and compared them using RHF/6-311G* and B3LYP/6-31G*. The experiments revealed that Na ion exchange has a significant effect on low-rank coal gasification. The model structure of low-rank coal is considered to change significantly in terms of the electronic state before and after Na exchange even with a simple main molecular structure. Molecular models where H of COOH/OH was ion-exchanged with one, two, and three Na ions were developed, and quantum chemical calculations were performed. The results showed that when the number of Na+-exchanged sites is increased, the electron state on the coal molecule becomes more negatively charged in the case of the Na+-exchange coal model. It is presumed that this contributes to enhancing the reactivity of low-rank coal and water vapor. In addition, weak bonds in the Na+-exchanged coal molecule were examined by calculating the difference in the value of the Mulliken and Löwdin bond orders before and after Na+ exchange. The results showed that the increase in the number of exchanged Na+ in the low-rank coal molecule model increased the number of weak bonds in the molecule. It is presumed that this contributes to enhancing the decomposition of low-rank coal.

    A model carbon prepared from phenolic resin was O-2-activated and then impregnated with Ca, Cu or Zn to clarify chlorine behavior in coal utilization. Ease of interaction between HCl and the carbon material was enhanced at 100-300 degrees C. The concentration at which HCl reacted with Ca, Cu and Zn was high. The surface chloric species that were generated by reaction of the carbon substrate with HCl were studied using X-ray photoelectron spectroscopy (XPS) and temperature programmed desorption (TPD). XPS measurements suggested the presence of inorganic chloride and organic chlorine species after reaction with HCl. When the carbon samples were washed after the HCl reaction, most of the HCl was eluted. Chemically adsorbed HCl species were also detected by TPD measurement; the presence of inorganic chloride, organic chlorine and chemically adsorbed HCl species were indicated. No correlation was determined between the amount of organic chlorine species generated and the number of activated carbon sites at 100 degrees C. However, the amount of organic chlorine at 300 degrees C indicated a tendency to increase with the number of carbon sites, and the surface functional oxygen groups acted as sites for the generation of C-Cl bonds. As a result, possible scheme for the generation of organic chlorine species at low temperature by reaction between HCl and the metal-doped (Ca, Cu or Zn) carbon is discussed.

    Calcium ion exchange was performed in Indonesian low-rank coal using saturated aqueous solutions of Ca(OH)(2) at 30.0 +/- 0.1 degrees C without pH adjustment. The Ca2+ concentration and pH were monitored during ion exchange. A coal product was obtained with 3.2 mass% Ca2+. Gasification of the ion-exchanged samples was conducted in a circulating dual bubbling fluidized bed (CDBFB) reactor at 700 degrees C, 800 degrees C, and 900 degrees C. Coal carbon conversion into carbonaceous gases (CO, CO2, CH4, and C-2 hydrocarbons) using the Ca2+-exchanged coal achieved 78% at 900 degrees C in the CDBFB. The Ca catalyst led to the greatest rate enhancement at 800 degrees C, resulting in a twofold increase in the gas product yield compared to that without Ca.A comparison of carbon conversion between the CDBFB and fixed-bed reactors revealed that the conversion value using the CDBFB at 700 degrees C was very small. Regarding an examination of this influence in detail, it seems that the existing H-2 adhered primarily to the active sites of the char, and the use of Ca2+-exchanged coal led to a reverse shift reaction.

    The optimum conditions for the production of high-surface-area activated carbon from peat were examined in a fixed-bed quartz reactor by using natural soda ash (> 99 mass% Na2CO3) as the activation agent and urea (CH4N2O) as the nitrogen source. In the heating of the peat/urea/Na2CO3 mixture, the surface area of activated carbon significantly increased when the temperature was higher than 700 °C, and it reached 940 and 1100 m2/g at 800 and 900 °C, respectively. When the mixture was also held at 700 and 800 °C for 1 h, the surface area drastically increased from 100 m2/g without holding treatment to 730 m2/g at 700 °C, and it became 1050 m2/g at 800 °C. The effect of the peat/urea/Na2CO3 mixing ratio on the increase in surface area was investigated. The ratio of urea to Na2CO3 was fixed at 1/2 and the proportion of peat was varied in the range of 0.5–2 the surface area was maximum when peat = 1. In another case, the ratio of peat to urea was fixed at 1/1 and the proportion of Na2CO3 was varied in the range of 1–4. In this case, the surface area was maximum (940 m2/g) when Na2CO3 = 2 but decreased when Na2CO3 = 4. On the other hand, when the ratio of peat to Na2CO3 was fixed at 1/2 and the proportion of urea was varied in the range of 0.5–3, the surface area markedly increased up to urea = 1 however, a significant increase did not take place thereafter, even when the proportion of urea was increased. According to these results, the optimum mixing ratio of peat/urea/Na2CO3 and heat treatment conditions to produce high-surface-area activated carbon from peat may be 1/1–3/2 and holding at 800–900 °C for 0–1 h, respectively.

    A model carbon prepared from phenolic resin was activated with O2 and then impregnated with Ca, Cu, or Zn to examine the relationship between the amount of HCl desorbed from carbon samples containing various metals in this lower temperature range (100 and 300 °C) and clarified the effect of active sites on HCl adsorption. The results showed that interactions between HCl and carbon were enhanced at temperatures in the range of 100-300 °C and that the amount of HCl reacted was increased by doping with these metals. The different HCl concentration profiles at 100 and 300 °C were obtained with a greater overall decrease in HCl at the lower temperature (100 °C). Those are attributed to increased physical adsorption of HCl at 100 °C. The mass of HCl reacted increased in the order of Cu < Ca < Zn at 300 °C and Ca < Cu < Zn at 100 °C, and HCl reacted at 300 °C was evidently more stable than that reacted at 100 °C. Organochlorine compounds, chemisorbed HCl, and inorganic chlorides were all identified on the carbon surfaces following exposure to a flow of HCl. The organochlorine species and chemisorbed HCl were desorbed, along with the generation of H2O, upon heating the samples to 700 °C, while inorganic chlorides and additional H2O were desorbed above this temperature. Both the mass of organochlorines generated and the amount of HCl absorbed were found to increase with the number of active sites at 300 °C however, that was exceeded remarkably at 100 °C.

    Ca2+ and Na+ cations were separately or consecutively ion-exchanged with an Indonesian low-rank coal using saturated aqueous solutions of Ca(OH)2 and/or soda ash at 20-40 °C without pH adjustment. This was done by adding aqueous solutions of the soda ash and/or calcium hydroxide to a dispersion of coal particles in deionized water, while monitoring the Na+ and Ca2+ concentrations and pH of the resulting mixture. A 3.5 mass % Ca2+-exchanged coal, a 1.6 mass % Na+-exchanged coal and a 3.8 mass % Ca2+- and 1.0 mass % Na+-exchanged coal were obtained. The catalytic pyrolysis and subsequent gasification of these ion-exchanged specimens were performed in a fixed bed quartz reactor at 650, 700, or 750 °C. X-ray diffraction analyses of the samples pyrolyzed at 700 °C found no evidence of Na or Ca species, indicating that these were present as nanoscale particles. The Ca2+/Na+-exchanged coal underwent steam gasification more readily than the other samples, with complete char conversion of this material following 1 h of processing at 700 °C. The use of a binary metal catalyst was also found to lower the required reaction temperature by more than 100 °C.

    The electronic states of anatase and rutile TiO(2) crystals and of TiO(2) crystals with Ti(4+) ions isomorphically replaced by various metal ions (V(3+), V(4+), V(5+), Cr(3+), Mn(3+), Fe(3+), Co(3+), Ni(2+), Ni(3+), and Rh(3+)) were calculated using the DV-X alpha method, which is a density functional method. It was found that the band gap changed in parallel to the radius of the replacing ion, except for a few cases. This tendency agrees with an experimental result in the literature that the light absorption band of anatase shifts to a longer wavelength region, when metal ions are injected. Calculations showed that the replacement of Ti(4+) by Ni(3+) and V(5+) gave the largest decreases in the band gap, suggesting that these metal ions are the most efficient replacing ions for TiO(2). The isomorphic replacement resulted in the formation of new energy levels of the metal 3d orbitals in the forbidden band of TiO(2). These levels seemed to interact with the 2p orbitals of oxide ions in TiO(2), resulting in a decreased band gap. An increase in the degree of covalent bonds between the replacing ions and the oxide ions probably contributes to the decrease in the band gap. (C) 2001 Elsevier Science B.V. All rights reserved.

    The vapor-phase Beckmann rearrangement mechanism of cyclohexanone oxime on oxide catalysts (SiO2-Al2O3 gamma-Al2O3, SiO2 and ZnO) was quantum chemically investigated using MOPAC 93. It was suggested that the rearrangement on the oxide surfaces proceeds via a fast step where a Bronsted acid site interacting with the nitrogen atom is transferred to the oxygen atom of the oxime. It was also suggested that the reaction then proceeds via a rate-determining step where the hydroxy group is eliminated with simultaneous alkyl group transfer as proposed for the liquid-phase rearrangement. The activation energies of the vapor-phase rearrangement of the oximes on the oxides were calculated on the basis of this suggested mechanism. The order of the activation energies for these oxides was in good agreement with that of the experimentally determined catalytic selectivities of E-caprolactam. This agreement indicates the validity of the mechanism proposed for the liquid-phase reaction by Landis and Venuto for the vapor-phase reaction. The proposal, suggested by Nguyen et al. for the liquid-phase reaction, in that the rate determining step is the transfer of the Bronsted acid, i.e. proton from the nitrogen atom to the oxygen atom of the oxime is invalid on oxide catalysts.

    DV-X,, calculations indicated the possibility of shifting the absorption edge of titania to the sunlight region by isomorphic substituting of a transition metal cation for a titanium ion. Among the cations addressed here, Ni3+ and V5+ reduced the band gap most effectively. The efficiency of the reduction by the substituting cation increased as the radius of the cation decreased.

    Using a semi-empirical molecular orbital method, PM3, and 2-propanol as an example, the dehydration and the dehydrogenation processes of alcohol on oxide catalysts were studied. The catalysts addressed here were four kinds of oxides (Al2O3, SiO2, ZnO, CdO) whose reaction selectivities had been experimentally determined. The usual models consisting of a surface metal ion, several oxide ions and an isopropoxy group were used in calculations. For the dehydration, heats of formation of the models were calculated at each point of the process where the distance between a beta-hydrogen of the group and a basic site (i.e. oxygen of the group or a surface oxide ion) or a metal ion was gradually shortened, or where the length of the C-alpha-O bond of the group was gradually increased. A reasonable dehydration mechanism was estimated by comparing activation energies calculated from the transitions of the heats of formation. The most probable dehydrogenation mechanism was also estimated in a similar way by gradually making an alpha-hydrogen close to a surface oxide ion, the metal ion or a surface proton. It was concluded that the dehydration proceeds by scission of the C-alpha-O bond of the group after its oxygen was attacked by some electrophile on the surface and that the dehydrogenation proceeds by a mechanism in which an alpha-hydrogen of the group was extracted by the metal ion. Based on the dehydration mechanism thus deduced, alkoxy groups generated by adsorption of the primary, secondary and tertiary alcohols on SiO2 were calculated in order to estimate the activation energies of their decompositions. In result, the order of the energies was found to be in good agreement with that of the decomposition rates experimentally determined by Kitahara. This agreement gives support to the validity of the mechanism deduced for the dehydration of alcohol. (C) 1999 Elsevier Science B.V. All rights reserved.

    On the isomerization of propylene oxide (PO) to propionaldehyde (PA) and/or acetone (AC) on five oxide catalysts (SiO2, Al2O3, MgO, ZnO and CdO), mechanisms and selectivity-controlling factors of the isomerization were studied by the MOPAC-PM3 semi-empirical calculation method. The validity of the mechanisms proposed so far was discussed by comparison of activation energies for the isomerization of PO with experimentally determined selectivity on the five catalysts. It was found that PO isomerizes to PA on a metal ion (Lewis acidic site) and that the selectivity depends on the net charge of the site, i.e., the PA selectivity increases with the net charge of the site. Active sites adjacent to the Lewis acidic site, which are the metal ions in case of SiO2, Al2O3 and MgO or the surface oxide ions in case of ZnO, are able to stabilize the reaction intermediate. It was concluded that the degree of the stabilization tends to increase as the bond length between the metal ion and the oxide ion decreases. The isomerization of PO to AC, however, was estimated to proceed without chemisorbing of the reactant on the surface of the catalyst.

    On the isomerization of propylene oxide (PO) to propionaldehyde (PA), acetone (AC), and allyl alcohol (AA) on five oxide catalysts (SiO2, Al2O3, MgO, ZnO, CdO), the mechanism and selectivity-controlling factors of the isomerization were studied by the MOPAC-PM3 semi-empirical calculation method. A reasonable mechanism was derived from requirement that the selectivity difference of the catalysts should be consistently interpreted by the calculated electronic states of PO. With regard to the selectivity-controlling factors, it was found that PA and AC selectivities correlate closely with net charges of Lewis acid site (surface metal ion) and basic site (surface oxide ion) on oxide clusters having formal charges of 1+ (Lewis acid site) and 1- (basic site), respectively. There was no correlation concerning AA selectivity. As the result, it was supported by computational chemistry that PA and AC selectivities are used as measures of surface acidity and basicity, respectively, of oxide catalysts. These results suggest that it is a simple and effective method to derive a reasonable reaction mechanism by comparative study of semi-empirical calculations with results of experiments on a series of catalysts.

    化学反応における化学種の濃度の時間変化を求めるために、反応速度式をRunge-Kutta法を用いて数値積分するプログラムを作成した。数値積分に際しては、反応に含まれる化学種の濃度の時間変化の大きさをチェックし、それに応じて積分間隔を適当に選択する手法を採用した。本プログラムを1) IO3-, H+, I2, I-, H2O2を含む溶液の振動反応、2) エステルのけん化反応、および3) 水素―臭素反応の3種類の反応に適用した。その結果、本プログラムを使用することによって、濃度の時間変化が比較的短時間で計算できることが確認された。
