Iron, molybdenum catalyst in kerosene handled in the catalytic properties


Of the group, on the one hand it is H ● ● 1 Zou Gang Ming iron, molybdenum catalyst in kerosene handled in the catalytic properties of H on IH: N: HI A of this part of the electronic cloud induced weakened N-H key, so that H ・ easily freed. Demonstrated its catalytic ammonium H; the other hand M0O a pair of H. S has also induced weakened HsH key to improve the concentration of active hydrogen. This store, and sulfur with the result that ammonium molybdate catalyst has been strengthened. 2.4 Catalyst methods people of different catalytic effect plus the literature [6], coal impregnation with FeSO, filtered vacuum drying, the liquefaction of coal hydrogenation reaction, the conversion rate. 0.05M FeSO used in the experiment the solution, add appropriate amount of ethanol impregnated coal 24 hours After filtration,[link widoczny dla zalogowanych], drying in a vacuum oven temperature 2 hours, was pre-coal samples, each with a different catalyst for the total treatment response, the results shown in Table 6 Table 6 by adding different catalysts after pretreatment of coal from the experimental results into slaughter by pretreatment of the coal fly ash in the future by adding sulfur and Shougang, a slight increase in coal conversion, and joined molybdenum catalyst the conversion decreased slightly. Yanzhou bituminous coal bituminous coal is a young side, because coal contains more carboxyl and phenolic hydroxyl oxygen groups in the use of FeSO. Impregnation process, the functional groups with metal ions to form hydroxyl carboxylic acid salt and salt, and tiny holes in the battlements adsorption, the catalyst easily penetrate into the inner and outer surfaces of coal to help the catalyst with full access to the coal sample, and the catalyst occupied the large number of active coal adsorption sites,[link widoczny dla zalogowanych], can fully serve as a catalyst catalyst. Pretreated coal, then add sulfur or Shougang,[link widoczny dla zalogowanych], fly ash,[link widoczny dla zalogowanych], catalyst to further enhance the catalytic activity than those without pretreatment of the coal conversion rate is higher. However, after pretreatment of the coal, because coal has absorbed large amounts of iron ions, when added molybdenum catalyst, is difficult to be adsorbed by coal, and molybdenum catalytic activity than iron-based catalyst in the results of suppressed molybdenum catalyst in the catalyst, leading to decline of coal conversion. 3 Conclusions (1) coal tar coal and low-temperature reactions were processed, Shougang fly ash, ammonium molybdate, molybdenum trioxide conversion of coal have a catalytic role, and the molybdenum catalyst in the catalytic activity than iron catalytic agent. (2) S has a distinct synergistic catalytic effect. (3) Catalyst addition method for conversion of kerosene handled in a certain effect,[link widoczny dla zalogowanych], was impregnated with catalyst solution better way coal. 1995, 66 coal conversion is
