| 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 H2S 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. |
