    摘要: A method for producing propylene including: transferring a feed gas including dimethyl ether and/or methanol and C4 and/or C5 olefins into a reactor, and reacting the feed gas in the presence of a catalyst, the feed gas prior to transferring into the reactor having a (supplied C4 and/or C5 olefins)/(supplied dimethyl ether and methanol) ratio of 0.25 to 7.5, in terms of the molar ratio based on the number of carbon atoms, and the feed gas being contacted with the catalyst at 350° C. to 600° C.; and an apparatus for producing propylene including: a hydrogenation reactor in which alkynes and/or dienes contained in C4 and/or C5 hydrocarbons is partially hydrogenated to be converted into an olefin having one double bond; a reactor in which C4 and/or C5 hydrocarbons is reacted with dimethyl ether and/or methanol in the presence of a catalyst; and a separator for separating propylene from the reaction product.

    摘要: 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.
