摘　　要：以神府煤为原料，研究了用硫化氢作氢源在间歇式高压反应釜中进行煤液化过程的可能性．重点考察了气体中H2S（硫化氢）的含量、催化剂种类对煤转化率的影响，并对S在液化油及残渣中的分布以及油品的组成进行了分析．实验结果表明：在氢源中加入H2S或全部以H2S取代时，煤液化条件在趋于温和化的同时转化率均有不同程度的提高，其中H2S加入量在20％～50％时，转化率可由原来的62％提高到70％左右．实验中还对单独以H2S作为氢源进行液化的催化剂效果进行了比较，发现FeS催化效果高于氧化物催化剂．The liquefaction possibility of Shenfu coal with H2S as the hydrogen source was studied in a high pressure batch autoclave. The factors, were investigated, that influenced on the conversion of coal liquefaction, included the proportion of H2S in hydrogen source and kind of catalysts, then both the distribution of S, in the liquefaction oil and residual, and the composition of the oil, were analyzed. Results showed that the liquefaction condition is getting mild and the conversion increased in various degrees when H2 S as the whole or part of hydrogen source, and when the proportion of H2S in hydrogen source is in the range of 20% - 50%, the conversion is increased from 62% to about 70% ; Besides, FeS showed a higher catalytic activity than the other metallic oxide with the hydrogen source of H2S.
