Abstract:
The present invention provides a method for producing Lower olefin from the feed of methanol or/and dimethyl ether, characterized in that methanol or/and dimethyl ether are divided proportionally to be fed at 3 reaction zones; and the desired distribution of the olefin product is obtained by modulating the feeding ratio among the 3 reaction zones and the reaction conditions in each reaction zone.
