摘　　要：为了寻找重质油催化加氢转化的新型催化剂,将活性炭用于大港减渣超临界萃取残渣的催化加氢,GC/MS分析结果显示,催化温度从350℃升至400℃,催化产物的收率从4.71%提高至21.03%.催化温度在350℃下,当活性炭用量从0.10 g提高到0.20 g时,催化产物的收率从4.71%提高至17.45%,活性炭和镍并用获得了协同效应.催化产物包括正构烷烃、支链烷烃、环烷烃、烯烃、芳香烃和含氧有机化合物,主要为柴油成分.活性炭对大港减渣超临界萃取残渣具有较好的催化效果.In order to find new catalyst employed in catalytic hydroconversion of heavy oil, active carbon （AC） is employed in catalytic hydroconversion of DVR SFER independent. Analysed results of catalysates by GC/MS indicate, when AC is employed under 350 ℃ and 400 ℃, yields of products reach respectively 4.71% and 21.03 %. When AC volume raise from 0.10 g to 0.20 g, yields of products under 350 ℃ ,4 h, 5 MPa reach 17.45 %. Synergistic catalytic hydrogenation of AC/Ni co-operation on DVR SFER acquires synergistic catalytic hydrogenation. Catalysates is mainly diesel oil including normal alkanes, chain alkanes, Cycloalkanes, alkenes, arenes and oxygen-containing organic compounds. AC employed in catalytic hydroconversion of DVR SFER pro- cesses good effect.
