摘　　要：考察了齐鲁石化胜利炼油厂北催化油浆 (FCC)和胜利减压渣油 (VR)在 4 90℃、0 .8MPa下不同混合比的原料和不同反应时间的中间产物的HS、TS、PS、PI及其 1h中间产物的HS和TS的1H NMR。数据结果反映了体系的反应速度。掺入FCC油浆抑制了VR的反应活性 ,降低了体系的反应速度 ,增加了基质的溶解度 ;1h中间产物的组成结构更接近于原料及反应体系的反应性和基质的溶解度 ,1h中间产物的芳香度越高 ,取代基越少 ,侧链越短 。The HS, TS, PS, PI of the compounds in vacuum residue (VR) after co-carbonisation with various ratios of fluid catalytic crack (FCC) slurry at 490 degreesC under 0.8 MPa for different times were determined. The HS and TS compounds of the products after reaction for 1 h were analyzed by H-1-NMR. The results showed that the FCC slurry additions moderated the reactivity of VR, decreased the reaction rate and increased the solubility of the reaction system for the large molecules formed in early stages of carbonization. This was reflected in the properties of the 1 h intermediate products indicating that the higher the aromaticity, the fewer substitute groups and the shorter the side chains, then the higher the solubility of the system.
