摘　　要：以煤焦油中难转化的酚油为原料,采用Ni、W负载的MgO和酸碱耦合剂为催化剂,在高压反应釜内对酚油催化加氢制环烷烃反应性能进行研究。结果表明:P改性MgO(P质量分数为0.8%)与酸碱耦合剂均能有效降低加氢催化剂结晶度、优化孔道结构、提高产物环烷烃和芳烃选择性;在Ni-W活性金属负载量(w)为9.0%时,催化剂选择性加氢活性最高,环烷烃选择性达到57.5%。煤焦油加氢的最佳工艺条件为:氢初压8.0 MPa,温度380℃,反应时间60 min。The catalytic hydrogenation of phenol oil to naphthene was studied in a high pressure reactor with both Ni-W supported MgO and acid-base coupling agent as the catalyst.The results showed that the modified magnesium oxide(0.8%by mass fraction)and acid-base coupling agent could effectively reduce the crystallinity of hydrogenation catalyst,optimize the pore structure,and improve the selectivity of cycloalkanes and aromatics.The hydrogenation activity of the catalyst was the highest at the Ni-W active metal loading of 9.0%,and the selectivity of naphthene reached 57.5%.The optimum conditions for hydrogenation of coal tar were:initial pressure of hydrogen 8 MPa,the temperature 380℃and reaction time 60 min.Preparing highly selective and highly active hydrogenation catalysts and processing coal tar to jet fuel are of great significance to replace part of petroleum resources in China.
