摘　　要：选用了两种催化剂进行催化转化热煤气中有机硫化合物的研究 ,实验表明 ,硫化态的 Ni基催化剂是一种高活性的有机硫转化催化剂 ,其转化活性可达 80 %以上。当气相含硫太低时 ,催化剂在使用过程中会失硫 ,转化活性下降。然而在实际的热煤气含硫的情况下 ,它显示出相当高的催化转化反应活性 ,适于在热煤气净化的条件下使用。A Nibased catalyst and a Mobased catalyst were selected for the hydroconversion of organic sulfur in hot coal gas. By using the comparison test, the reactivity of Nibased catalyst is higher than Mobased catalyst. It is found that the loss of sulfur in sulfurized catalyst for both catalysts will be observed when sulfur content in inlet gas is lower than 0.1%, however, the sulfur content in practical coal gas is enough to avoid the phenomenon. The Nibased catalyst is a commercial hydroconversion catalyst of organic sulfur and it can be used effectively for the hydroconversion of organic sulfur in hot coal gas. Higher conversion (>80%) of organic sulfur is attained at simulated cleaning up conditions for hot coal gas.
