| 摘 要： | 采用程序升温法制备了Mo2C/SAPO-11催化剂，以正庚烷为模型分子，在固定床连续流微反装置上考察了分别采用正戊烷和正庚烷做碳源，对催化剂制备和异构化的影响。在400 ℃，氢压1.5 MPa，氢烃体积比为200∶1，空速1 h-1条件下，正庚烷转化率达到81.39%，选择性68.67%，异构产物收率55.89％，连续反应120 h，异构化活性未见明显降低。

| Abstract: | SAPO-11 supported molybdenum carbide catalyst was prepared by TPR using different carbon sources. The influence of carbon sources on preparation of Mo2C/SAPO-11 catalyst and its catalytic behaviors for hydroisomerization of nheptane were investigated in a fixed bed down flow reactor．The results showed that selectivity to isomers of 68.67%, isomers yield of 55.89% and n heptane conversion of 81.39% were obtained under following condition: 400 ℃, 1.5 MPa, LHSV 1.0 h-1, hydrogen/hydrocarbons volumetric ratio 200∶1. No considerable decline of the catalytic activity was observed after continuous reaction for 120 h. |
