Abstract

See full text

The invention relates to a process of converting methanol in a fluidized bed reactor comprising feeding a methanol-containing feedstock into a fluidized bed reactor, contacting the feedstock with a catalyst, to produce a product comprising ethylene and propylene under effective conditions; 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 % (preferably more than 0.01 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 % (preferably more than 0.01 wt %) in the fluidized bed reactor is controlled to be less than 10° C.
