Abstract
Disclosed is a multistage process for converting lower aliphatic oxygeanated hydrocarbon feedstock to hydrocarbon product rich in benzene, toluene and/or xylene which comprises: contacting said oxygenated hydrocarbons in a primary stage with a medium pore shape selective acidic zeolite to an intermediate hydrocarbon product comprising predominantly aliphatic hydrocarbons; contacting at least a portion of the aliphatic hydrocarbons from the primary stage with a secondary stage catalyst comprising gallium-promoted medium pore shape selective zeolite characterized by a constraint index within the approximate range of 1 to 12 and a silica to alumina ratio of about 20 to 100:1; thereby producing benzene, toluene and/or xylene.
