Other AbstractThe present invention provides a process for methanol coupled catalytic cracking reaction of naphtha using a modified ZSM-5 molecular sieve catalyst, comprising performing a co-feeding reaction of methanol and naphtha on the modified ZSM-5 molecular sieve catalyst to produce low carbon olefins and/or aromatic hydrocarbons. In the process, the modified ZSM-5 molecular sieve catalyst comprises, in term of weight percent, 25-80wt% of a ZSM-5 molecular sieve, 15-70wt% of a binder, and 2.2-6.0wt% of lanthanum and 1.0-2.8wt% of phosphorus loaded on the ZSM-5 molecular sieve. The naphtha comprises 63.8-89.5 wt% of saturated chain alkanes and 5.6-29.8wt% of cyclic alkanes. The naphtha and methanol concurrently pass through the catalyst bed, which are reacted during contacting with the catalyst under a reaction condition of a reaction temperature of 550-670°C, a mass ratio of methanol to naphtha of 0.05-0.8, and a total mass space velocity of naphtha and methanol of 1.0-5 h -1 . | 本发明提供一种采用改性ZSM-5分子筛催化剂催化甲醇耦合石脑油催化裂解反应的方法,所述方法包括将甲醇和石脑油在改性ZSM-5分子筛催化剂上进行共进料反应,以生产低碳烯烃和/或芳烃。在所述方法中,所述改性ZSM-5分子筛催化剂以重量百分比计包含25-80wt%的ZSM-5分子筛、15-70wt%的粘结剂,和载于所述ZSM-5分子筛上的2.2-6.0wt%的镧和1.0-2.8wt%的磷。在所述石脑油中,饱和链状烷烃占63.8-89.5wt%,环烷烃占5.6-29.8wt%。石脑油与甲醇同时通过催化剂床层,与催化剂在反应温度为550-670℃、甲醇与石脑油质量比为0.05-0.8、石脑油和甲醇的总质量空速为1.0-5h-1的反应条件下接触反应。
