摘　　要：以中低温煤焦油为原料,在高压釜中模拟了煤焦油悬浮床加氢预处理过程,在自制非均相催化剂作用下,探索反应条件对液体产物分布及甲苯不溶物(TI)转化率的影响规律。结果表明,反应温度和氢初压的升高以及催化剂添加量的增加可以显著提高轻油(汽油、柴油馏分)收率,在反应温度为460℃、氢初压为16.0 MPa、催化剂添加量(w)为3.0%、反应时间为1.0 h的条件下,液体产物轻油收率达54.21%,TI转化率达到86.5%,产物分布得到显著改善。The pro-hydrotreating of mid-low temperature coal tar was conducted in a magnetic-stirred autoclave to simulate the reaction situation of the slurry-bed.Using the self-designed heterogeneous catalyst LN,the effect of reaction conditions on product distribution and the conversion of toluene insoluble was explored.The results showed that the yield of light oil was improved with the increase of the temperature and the initial hydrogen pressure.At a reaction temperature of 460℃,a initial pressure of hydrogen of 16.0 MPa,a mass ratio of catalyst to coal tar of 3.0%,a the reaction time of 1.0 h,the yield of light oil and the conversion of toluene insoluble reached 54.21%,86.5%,respectively.The product distribution was significantly improved.
