Abstract:
A process for producing light olefins from methanol and/or dimethyl ether is disclosed. It comprises: (a) introducing a feed comprising methanol and/or dimethyl ether into a fluidized-bed reactor from its bottom, and contacting the feed in a dense phase zone and a transition zone of the fluidized-bed reactor with a catalyst, to form an effluent I comprising unreacted feed, reaction products and entrained solid particulate catalyst; (b) introducing a terminating agent consisting of water, alcohol, ether, hydrocarbons, and aromatic at upper portion of the transition zone and/or lower portion of a gas-solid separating zone of the fluidized-bed reactor into the effluent I, to give an effluent II; and (c) passing the effluent II into the gas-solid separating zone in upper portion of the fluidized-bed reactor, where gas-solid separation is accomplished to give a gaseous product stream and solid catalyst.
