High octane gasoline and distillates from oxygenates

摘要

An integrated process for the conversion of methanol to high octane gasoline and distillate. Methanol is converted to olefins in the presence of zeolite type catalyst. C4 and C5 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 C3, C6 and C7 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.
