Abstract
A process for converting oxygenated feedstock, such as methanol, dimethyl ether or the like, to liquid hydrocarbons. In the primary catalyst stage the feedstock is contacted with zeolite catalyst to produce C.sub.2 -C.sub.4 olefins and C.sub.5.sup.+ hydrocarbons. In a secondary catalytic stage with oligomerization catalyst comprising medium-pore shape selective acidic zeolite at increased pressure converts C.sub.3.sup.+ olefins to gasoline and/or distillate liquids. The improvement is a technique for recovering lower alkene for recycle to the primary catalytic stage.
