PROCESS FOR CATALYTIC CRACKING NAPHTHA COUPLED WITH METHANOL USING MODIFIED ZSM-5 MOLECULAR SIEVE CATALYST |
摘要 |
The 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 . |
