Abstract
The present process provides a method for converting an oxygenate-containing feed stream to an olefin-containing product stream. The method includes: (1) providing a first fluidized catalytic reactor for converting methanol to propylene, the first reactor having a fluidized catalyst system comprising a first catalyst and a second catalyst; (2) providing a second fluidized catalytic reactor communicating with the first fluidized catalytic reactor for cracking heavy olefins having four carbon atoms or greater into propylene, the second reactor having the fluidized catalyst system; (3) providing an oxygenate containing feed to the first reactor; and (4) fluidizing the catalyst system with the oxygenate containing feed.
