甲醇制清洁油品催化剂级配工艺研究
|
摘要
介绍甲醇制汽油催化剂级配技术。通过不同酸中心数量和酸强度分布的催化剂级配实验发现,与单一类型催化剂相比,采用级配装填方式可以使催化剂性能互补,单程汽油收率大于70%;在保证甲醇完全转化情况下,改变气体产物分布,进一步提高目标产品收率,催化反应所得汽油中的芳烃含量降低,异构烷烃含量增加,改善了油品质量。
The gradation technology of methanol to gasoline catalyst was introduced. Through grading experiments of catalysts with different distribution of acid centers and acid strength,it was found that the performance of the catalyst could be complementary compared to single type catalyst. Single-pass yield of gasoline was higher than 70%. Under the condition of complete methanol conversion,the gas product distribution was changed,yield of target product was increased. Content of aromatic hydrocarbons in gasoline was reduced while content of isoparaffins was increased so as to improve quality of oil.
