ZSM-5 / ZnVPI-8 zeolite catalyst composite structure

The present invention relates to species ZSM-5 / ZnVPI-8 zeolite catalyst composite structure, preparation and use, mainly solves the prior art is the use of methanol to olefins catalyst stability is not high, in addition to the light olefins ethylene and propylene, isobutylene low selectivity, low yield problem. The present invention uses seed ZSM-5 / ZnVPI-8 zeolite catalyst composite structure, characterized in that the catalyst is in weight percent, comprising the following components: a) 10 ~ 100% of the ZSM-5 / ZnVPI-8 zeolite composite structure; B ) 0 to 90% binder technical solution solves this problem, it can be used in industrial production of methanol to olefins.
