Abstract
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,nIHPW/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%.
 
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 reaction350 ℃; H2/ decane volume ratio of 3000; total pressure of 2 MPa and the LHSV = 2 h-1.
