Beschreibung
Zusammenfassung:	In a process for production of lower hydrocarbons from dimethyl ether and/or methanol and an apparatus for the production, the object is; to increase the selectivity of the reaction product to thereby produce a target product at a high final yield, to prolong the catalyst lifetime, and to improve the safety in the operation of the apparatus. An apparatus to be used includes: a reactor 2 which reacts dimethyl ether and/or methanol in the presence of a catalyst to produce lower hydrocarbons; a separator 4 which separates ethylene from lower hydrocarbons from the reactor 2; and a converter 6 which converts the ethylene separated by the separator 4 into a hydrocarbon having 4 or more carbon atoms, and feeds this hydrocarbon into the upstream or downstream of the reactor 2.
