摘要:
考察了温度、压力、氢油比和原料液体空速等对Ni-HPW/Al2O3催化剂上正癸烷加氢裂化反应活性及产物分布的影响，通过优化催化剂最适宜的反应工艺，增加中间馏分油收率.结果表明，Ni-HPW/Al2O3催化剂适宜的反应条件为：反应温度350 ℃，反应压力2 MPa，液体空速2.0 h-1，氢油体积比3000.在此条件下，正癸烷转化率为52%，C5+选择性为67%.
Abstract:
The influence of reaction temperature,pressure,LHSV,and H2/decane ratio on the distribution of hydrocracking products over the Ni-HPW/Al2O3 for n-decane hydrocracking was investigated.The middle distillate yield was increased by optimizing the appropriate reaction process of catalyst.The best catalytic performance is displayed by the reduced Ni-50%H3PW12O40/Al2O3 catalyst,giving a decane conversion 52% and C5+ selectivity 67% under the following experimental conditions:temperature of reaction 350 ℃;H2/decane volume ratio of 3000;total pressure of 2 MPa and the LHSV=2 h-1.
