ジャーナル フリーAs a part of the investigation of the nickel-catalyzed gasification of coal which was pretreated with liquid ammonia, the caking properties of the treated coals were studied. The crucible swelling number was determined, and also the caking behavior of coal in a fluidized bed was observed with the naked eye. The ammonia treatment together with nickel impregnation makes the caking property decrease. Some coal lost its caking property upon ammonia treatment and exposure to air. The coals with the crucible swelling number less than 1 can be handled in a fluidized bed. Slow heating rates made it possible to handle coals with higher caking tendency. The crucible swelling number was f ound to be a good indication to judge the possibility of fluidizability of coal, whether it was an original one or a treated one.抄録全体を表示PDF形式でダウンロード (1103K) -

ジャーナル フリーTaiheiyo coal was treated with alcohol-alkali for 1hr at 300-430 t and the products were mixed with Taiheiyo coal in the ratio of 10, 20 and 30%. This mixtures were briquetted under the pressure of 5.3t/cm2 and then the briquettes were carbonized at 950°C
The binder ability of the reaction products was tested by measuring the compressive strensth of these carbonized briquettes.
The compressive strength increased with the content of binder (reaction product) in the briquette, which means that these reaction products have really the binder ability. The reaction product treated at 370°C showed the highest compressive strength. The products treated at lower temperature than 370°C have the higher softening point and those treated at higher temperature have the lower carbonization yield, which cause the lower compressive strength.
It is expected to have better results by using more adaptable coal as the starting coal of reaction and by selecting more suitable coal for base coal of briquetting.抄録全体を表示PDF形式でダウンロード (473K) -

ジャーナル フリーIn preceding paper it became clear that the secondary methane evolution occurs under certain experimental conditions on pyrolysis of coal.
In order to study more deeply the secondary methane evolution, the evolution rate of methane and hydrogen were measured simultaneously for Omine anthracite and Taiheiyo coal. The secondary methane evolution was accompanied with corresponding decrease in hydrogen evolution. It is suggested that the secondary methane evolution occurs according to equation C+2H2=CH4 on an average and is proportional to evolved hydrogen partial pressure.
Additional experiments were carried out using flow type high pressure thermo-balance in order to examine the influence of pressure on the weight loss of sample. It was found that the weight loss of sample were not affected by pressure applied. This leads to the conclusion that the inert gas pressure has not substantial effect on the evolution rate of primary tar.抄録全体を表示PDF形式でダウンロード (1019K) -

ジャーナル フリーFor the purpose to explore catalysts with high activity and durability and a new process for the reforming of CH4, various Al2O3 supported metal catalysts and the effect of the composition of reaction gases were studied.
The experiments were carried out by using a flow reactor under an atmospheric pressure and at 450°-950°C. The inlet gases were 10%CH4-10-40%H2O-N2, 10%CH4-10% CO2-N2, 10%CH4-5%02-N2, 10%CH4-5-10%H20-2.5-7%O2-N2, 10%CH4-5%CO2-2.5%O2-N2, 10%CH4-5%H2O-5%CO2-N2, etc., the total feed rate was mainly 1000Ncm3/min per 1ml of each catalyst with average diameter, 0.9mm and space velocity was 6.0×104hr-1.
The main results were obtained as follows: (1) The order of apparent activity for steam reforming was 10%Ni>0.3%Ru, 0.3%Rn, 10%Co>0.3%Pt> 0.3%Pd>10%Fe.(2) It is desirable to pre-calcine the commercial γAl2O3 at 11.00°C to form αAl2O3 before the impregnation into Ni (NO3) 2 aq., RuCl3-NH3 complex aq. and etc., and then to reduce in flowing H2 from room temperature to 500°C under increasing and then constant temperature.(3) The synthesis gas (CO+H2) was prepared by using the inlet gases of stoichiometric mole ratio of the following apparent reaction equations.
CH4+H2O→CO+3H2, CH4+CO2→2CO+2H2, CH4+ (1/2) O2→CO+2H2, CH4+ (1/2) H2O+ (1/2) O2→CO+ (5/2) H2, CH4+ (1/2) CO2+ (1/2) O2→ (3/2) CO+2H2, CH4+ (1/2) H2O+ (1/2) CO2→ (3/2) CO+ (5/2) H2抄録全体を表示PDF形式でダウンロード (2203K) -

ジャーナル フリーFor the purpose of exploring the prooess to prepare synthesis gas (CO+H2) or H2 from methanol, thermal decomposition (CH3OH→CO+2H2) and steam reforming (CH3OH+H2O→CO2+3H2) were investigated on Al2O3 supported metal (Pt, Pd, Ru, Rh, Co, Ni, Fe) catalysts.
The experiment was carried out by using a flow fixed bed reactor under an atmospheric pressure and at 300°-550°C. The inlet gases were 10%CH3OH-N2 and 10%CH3OH-40%H2O-N2, and the total feed rate was 500 Ncm3/min Per 1ml of each catalyst of average diameter 0.9mm (space velocity: 3.0×104 hr-1).
The following informations were obtained:
1) Decomposition of CH3OH under the absence of catalyst occurred at above ca. 700°C according to CH3OH→CO+2H2, but the decomposition under the presence of catalysts except Ru and Fe occured at low temperatures below 300°C.
2) Catalytic steam reforming was considered to be the consecutive reactions of CH3OH→CO+2H2 and CO+H2O→CO2+H2O. Ru and Fe gave a litlle activity.
3) Pt was the most active for both reactions, and gave no formation of CH4.
4) Pd was very high active for decomposition of CH3OH, but low active for shift reaction of CO.
5) Rh was active for both reactions, but accompanied the formation of a considerable amount of CH4.
6) Co gave the formation of equimolal CH4 and CO2 besides CO and H2 at decomposition of CH3OH, and was very high active for shift reaction of CO as well as Pt.
7) Ni promoted considerably the methanation reactions in both reaction systems.抄録全体を表示PDF形式でダウンロード (1274K) -

ジャーナル フリーThe oxidation of ammonium sulfide with ammonium 1, 4-naphthoquinone-2-sulfonate as a redox catalyst in aqueous solutions was studied in a stirred vessel at pH 8.5-9.9 and 22-40°C
It was found that the over-all oxidation rate at HS->2mol/m3 was determined by diffusion rate of oxygen, and conformed to the theory of absorption with pseudo first-order reaction. And the oxidation rate in aqueous solutions was expressed in the following equations,
-(HS-) /dθ=k1 (Cat) (O2) (kg-mol/m3hr)
k1=1.81×1016exp (-1.08×104/RT)
On the other hand, it was found that the over-all oxidation rate at HS-<2 mol/m3 was determined by the reaction Tate in aqueous solutions, and was expressed in the f ollowing equations,

ジャーナル フリーTo develop a simulation-model of the Hokkaishi-coal gasification pilot plant, a kinetic analysis of coal-char gasification was investigated. Experiments were conducted on the elementary reaction of C-CO2 and C-H2O.
Taiheiyo char pre-treated at 600°C same as fed-char into the pilot plant was used as the test samples. Samples were gasified in a 28 mmφ small batch type fluidized bed reactor made of quartz.
Reaction rate of the carbon was determined from the observed data of the produced gas.
Both reaction processes of C-H2O and C-CO2 were predicted considerably well by a modified mathematical model of unreacted core, namely the rate constant of intraparticle diffusion was corrected dividing by square of unreacted carbon conversion.
The activation energy of the C-H2O reaction was 31.2 kcal/mole and 38.5 kcal/mole for the intraparticle diffusion and interfacial reaction respectively. And also, the activa-tion energy of the C-CO2 reaction were 94.5 kcal/mole, and 44.1 kcal/mole respectively.
From the results of measured values dx/dt, it was confirmed that the C-H2O reaction processed superiorly as compared with the C-CO2 reaction.抄録全体を表示PDF形式でダウンロード (805K)
