ABSTRACT:
An integrated reactor system for conversion of methanol to ether-containing high octane gasoline and distillate. Methanol is converted to olefins in the presence of zeolite MTO catalyst. C.sub.4 and C.sub.5 olefin fraction is converted to MTBE and TAME in the presence of excess methanol and acid etherification catalyst. Unreacted methanol and hydrocarbons are passed to an olefins to gasoline and distillate oligomerization unit in conjunction with C.sub.3, C.sub.6 and C.sub.7 olefins from the methanol to olefins unit whereby distillate and LPG products are produced. Gasoline products from the oligomerization unit are passed to the etherification unit whereby an ether-rich gasoline fraction is separated.
