摘　　要：以克拉玛依常压渣油为原料,在温度442℃、氢压7.00 MPa、反应1 h的条件下,通过建立抑焦试验方法即釜式加氢裂化反应,研究了渣油悬浮床加氢裂化反应的5种催化剂,测定了5种催化剂在同等条件下反应的生焦量。通过添加催化剂与空白试验进行对比,发现3#催化剂能够使反应生焦量大大减少,焦的性状由块状颗粒变为油状柔软焦。将釜反应产物进行蒸馏试验后,添加催化剂和空白试验所得的4组分收率相差很小。With take KLAR atmospheric residue as raw material, under the conditions of the temperature of 442℃, hydrogen pressure of 7.00 MPa and reaction time of 1 h, by the establishment of a scientific experimental method for suppressing coke hydrocracking reaction （kettle-type hydrocracking reaction）, five kinds of catalysts for residue hydrocracking reaction in slurry-bed has been inspected, and the amounts of raw coke with five kinds of catalysts under the same reaction conditions are determined. Compared with the blank experiment, It＇ s found that the amount of raw coke could be significantly reduced with adding of 3# catalyst, and the coke characters has also been changed from massive particle into oil-like soft coke. a very small difference is shown between the yield of the four components and the blank experiment after the distillation of products.
