Abstract
An apparatus 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 a fluidized 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. A portion of the recovered gasoline stream is recycled to the fluidized bed at a point above the bed stratum corresponding to substantially complete oxygenate conversion.
