ABSTRACT:
An improved system for converting crude aqueous methanol feedstock or the like to olefinic hydrocarbons in contact with a medium pore shape selective crystalline acid zeolite catalyst, wherein the improvement comprises feedstock preparation means contacting the aqueous methanol feedstock with a liquid propane-rich hydrocarbon extractant under liquid extraction conditions, means for recovering an aqueous phase containing the major amount of water introduced with the feedstock, means for recovering an organic extract phase comprising the hydrocarbon extractant and a portion of methanol introduced in the feedstock, and reactor means for converting the extracted methanol at elevated temperature under catalytic reaction conditions to produce predominantly olefinic hydrocarbons.
