This patent describes an integrated fluidized bed process for the conversion of C{sub 1}-C{sub 5} oxygenate feedstock to olefinic gasoline range hydrocarbons and heavier distillate range hydrocarbons. It comprises: contacting the C{sub 1}-C{sub 5} oxygenate feedstock with shape selective medium pore metallosilicate catalyst in an oxygenate to light olefins conversion zone under oxygenate to light olefins conversion conditions whereby an effluent stream comprising C{sub 2}+ olefins is produced; cooling the effluent stream and passing the effluent stream to an olefins to gasoline conversion zone in contact with shape selective medium pore metallosilicate catalyst under olefins to gasoline conversion conditions whereby C{sub 2}+ olefins are converted to gasoline comprising C{sub 5}+ olefinic hydrocarbons; introducing the C{sub 5}+ hydrocarbons into an olefins to gasoline and heavier distillate range hydrocarbons conversion zone at increased pressure under olefins to gasoline and heavier distillate range hydrocarbon conversion conditions in contact with shape selective medium pore metallosilicate catalyst whereby olefinic gasoline and heavier distillate range hydrocarbons are produced without recycling C{sub 3}-C{sub 4} hydrocarbons to the olefins to gasoline and heavier distillate range hydrocarbons conversion zone.
