摘　　要：实验选用两种铁盐,采用催化剂预分散在原料油中以及预担载在原料煤上两种催化剂制备方法,并将制备的催化剂应用于煤油共处理反应体系中考察其对产物组成和性质的影响.结果表明,负载型催化剂较分散型催化剂与反应体系的适应性更好,Fe2+较Fe3+与反应体系的适应性好.由此可知,四种催化剂催化效果的优劣顺序为:负载Fe2+>负载Fe3+>分散Fe2+>分散Fe3+;此外,催化剂的催化效果越好,中间产物前沥青烯向液化产物沥青烯的转化越彻底,减压尾油中重组分向轻组分转化程度越大,液化残渣中催化剂的聚结程度也越小.Two catalyst precursors, and two catalyst preparation methods （dispersed catalyst in oil and impregnated catalyst on coal） were used in this experiment, then being applied in coal/oil co-processing system in order to inspect the effect on product composition and nature. It was found that impregnated catalyst had a better adaptability with the reaction system than dispersed catalyst, and also Fe^2＋ had a better adaptability with the reaction system than Fe^2＋, therefore the order of catalytic effect was impregnated Fe^2＋ 〉impregnated Fe^3＋ 〉 dispersed Fe^2＋ dispersed Fe^3＋. Moreover, the better the catalytic effect was, the more degree of PA transformation into Toluene-soluble liquids, the more degree of （R＋At） transformation into （S＋A） in VR, the smaller degree of coalescence was in liquefaction residue.
