Abstract
The present invention provides a reactor system for converting an oxygenate-containing feed stream to an olefin-containing product stream. The system includes: (1) 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) 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) wherein the first catalyst is a non-zeolite molecular sieve catalyst; and (4) wherein the second catalyst is a zeolite molecular sieve catalyst.
