摘　　要：使用工业催化剂Ni-Mo/Al2O3,在固定床反应器上对360℃前馏分煤焦油进行加氢处理实验,研究反应温度(320~400)℃对煤焦油加氢产物分布及化学组成的影响。实验过程中,反应条件设定为:压力10 MPa,空速0.5 h^(-1),氢油体积比1 600∶1。使用GC-MS分析煤焦油加氢前后的化学组成变化,结果表明,升高反应温度对煤焦油中芳烃类物质的加氢饱和反应不利,但有利于杂原子的脱除以及油品的轻质化。煤焦油中最主要的两类化合物是烷基萘与酚类物质,加氢过程中主要转化为二环癸烷与烷基环己烷。The hydrotreatment of low temperature coal tar was carried out in a fixed bed reactor by using Ni-Mo/A1203 catalyst. The effects of reaction temperature （320 -400） ℃ on distribution and chemical composition of hydrogenated products of coal tar were investigated. The reaction condition during the ex- perimental process was determined as follows： pressure 10 MPa, space velocity 0.5 h- 1, volume ratio of hydrogen to oil 1 600： 1. The feedstock and the product were analyzed by GC-MS. The results showed that increasing reaction temperature was beneficial to the hetero atom removal and oil upgrading but had a negative impact on hydrogenation of aromatics in coal tar. Two kinds of the main compounds in coal tar were naphthalene and phenol, which were transformed into decahydronaphthalene and eyclohexane respec- tively during hydrogenation.
