16 Claims

1. A process of converting methanol in a fluidized bed reactor comprising feeding a methanol-containing feedstock into a fluidized bed reactor, and contacting the feedstock with a catalyst, to produce a product comprising ethylene and propylene under effective conditions; wherein the fluidized bed reactor comprises a diluent-phase zone and a dense-phase zone, wherein the diluent-phase temperature difference between any regions of the diluent-phase zone having a methanol concentration of more than 0.1 wt % in the fluidized bed reactor is controlled to be less than 20° C., and the dense-phase temperature difference between any regions in the dense-phase zone having a methanol concentration of more than 0.1 wt % in the fluidized bed reactor is controlled to be less than 10° C.
