摘　　要：以重整抽余油为研究对象，考察了Ni基催化剂存在时，不同反应温度、压力、体积空速下加氢脱除不饱和烃的效果，研究表明采用Ni基催化剂，在150℃、1．0MPa、2．0h。条件下进行加氢反应，可使重整抽余油产品油的碘值降至0．09g／100g，不饱和烃含量较低。采用GC-MS进一步分析了加氢处理前后重整抽余油的组成分布，加氢前重整抽余油主要由C5～C9的烃类组成，其中C6～C8的正构和异构烷烃占主导，同时含有部分C6～C7的烯烃和C8～C9芳烃。加氢后的产品油仍以C6～C8的烷烃为主，不含烯烃，烯烃加氢产物含量明显增多，除含有少量C8～C9芳烃外，还存在部分芳烃加氢产物C8～C9环烷烃。The reforming raffinate oil was hydrotreated under Ni catalyst at different temperature, pressure and LHSV to investigate the removal effect of unsaturated hydrocarbon. The research shows that the iodine value of reforming raffinate oil can be reduced to 0.09g/100g by hydrogenation under the conditions of Ni-based catalyst, reaction temperature at 150℃, reaction pressure at 1.0MPa, LHSV 2. Oh-1 , and the content of unsaturated hydrocarbons is lower. Then the structure and composition of reforming raffinate oi were analyzed using GC-MS before and after hydrogenation. The reforming raffinate oil is mainly composed of Cs-C9 hydrocarbons before hydrogenation, in which C6--C8 n-alkanes and isoparaffins are dominant, and contains part of C6-C7 olefins and C8-C9 aromatics. The hydrogenated product oil is still dominated by C6--C8 alkanes, but doesn＇t contain olefin, in which the content of product from olefin hydrogenation increases. In addition, there are a few C8-- C9 aromatics and part of aromatics hydrogenation product Ca-- C9 naphthenics in the product oil.
