Abstract: Shengli vacuum residue with different amount of resin as raw materials was hydrotreated in an autoclave. Elemental analysis, measurement of molecular weight , simulated distillation and content analysis of metal (Ni, V) were performed on oil samples before and after hydrotreating. The results showed that compared with the raw materials, the average relative molecular mass, the sulfur content, the nitrogen content and the metal content of hydrotreated liquid products of Shengli vacuum residue with different amount of resin decreased, while the H/C ratio increased. With the increase of resin amount, the average relative molecular mass, the H/C ratio of liquid products of hydrogenation increased, and the sulfur content decreased, while the content of nitrogen and metal decreased first and then increased. With the increase of resin amount, the yield of gasoline and gas, hydrogenation residue oil and coke reduced, while the yield of diesel and gas oil distillate increased.

Key words: resin, dosage, vacuum residue, hydrogenation, product distribution
