摘　　要：以孤岛减压渣油为原料 ,采用高压釜加氢方式考察了以钴、钼、镍、铁和稀土金属为活性组分的 2 1种催化剂对渣油悬浮床加氢裂化反应的作用。结果表明 ,在钴、钼、镍系列催化剂中 ,钼系催化剂的效果较好。其中 ,钼酸铵系列最佳 ;钴系与镍系催化剂的效果相当 ;铁系催化剂中的硝酸铁具有较高的活性和抑制甲苯不溶物生成的能力 ;稀土系列催化剂的活性远高于钴、钼、镍、铁系列催化剂 ,其产物中减压馏分油的收率较高 ,而且这种催化剂抑制甲苯不溶物生成的潜力较大 ,可以在更苛刻的反应条件下与减压渣油反应。首次采用相对效率因子 fr 来评价悬浮床加氢裂化催化剂的活性 ,与分极指数RN相比 ,frTwenty one kinds of catalysts containing metals, such as cobalt (Co), molybdenum (Mo), nickel (Ni), iron (Fe), cerium (Ce) and lanthanum (La), were used as the catalysts for slurry bed hydrocracking of Gudao vacuum residue. The experiment was performed in a batch reactor. The results show that ammonium molybdophospate is more efficient among series of molybdenum, cobalt and nickel catalysts. The series of cobalt and nickel catalysts are on the same level. Iron nitrate in iron series has higher activity than other iron containing in catalysts. Rare earth series of lanthanum or cerium catalysts combined with nickel has higher activity than others in hydrocracking reaction. The yields of vacuum fraction are high when rear earth catalysts are used. The relative efficiency factor can be used to evaluate the activity of catalysts.
