三种直接液化催化剂的活性和选择性对比研究

STUDY ON REACT ACTIVITY AND SELECTIVITY OF THREE DERECT LIQUEFACTION CATALYSIS

对神府煤田1#煤和2#煤进行了三个不同催化剂条件下的加氢液化实验研究,在不同催化剂条件下,两个煤样的液化转化率和油产率曲线呈现不平行的趋势,分析可知,这是由于不同催化剂作用在液化反应不同阶段的催化效力的不同造成的;三种催化剂中催化活性最好的为合成催化剂,Fe2O3次之,天然硫铁矿较差;而就选择性而言,天然硫铁矿好于Fe2O3,合成催化剂的活性和选择性都要优于前两者.

Two coal samples from Shenfu zone were hydrogenated liquefied under three different catalysts. Under different catalyst, their curves of convert ratio and oil yield show dissimilar tendency. Because each catalyst has various effect in different react course. In three catalysts, the synthetic catalyst show best activity and selectivity. Fe2O3 is better than pyrite in activity and worse in selectivity.
