Title: Integrated reactor system for converting oxygenates to alkylated liquid hydrocarbons

Abstract

This patent describes an integrated continuous system for converting oxygenated organic feedstock to liquid hydrocarbons including: first reactor means for contacting feedstock with zeolite catalyst in a primary catalyst stage at elevated temperature to convert at least a portion of the feedstock oxygenate predominantly to C/sub 2/-C/sub 4/ olefins and a minor liquid fraction containing C/sub 5//sup +/ liquid hydrocarbons; first separator means for cooling and separating effluent from the first reactor means to provide an aqueous liquid byproduct stream, a C/sub 5//sup +/ liquid hydrocarbon stream and a light hydrocarbon vapor stream rich in C/sub 2/-C/sub 4/ olefins; means for compressing at least a portion of the olefinic light hydrocarbon stream to condense a C/sub 3//sup +/ liquid olefin hydrocarbon stream rich in C/sub 3/-C/sub 4/ olefins and recovering an ethene-rich gaseous stream; adsorption means for contacting the ethene-rich gaseous stream from compressing means with a liquid hydrocarbon sorbent stream in a sorption tower under conditions to selectively sorb the major amount of C/sub 3//sup +/ hydrocarbon components from the gaseous stream to provide a C/sub 3//sup +/ sorbate stream rich in C/sub 3/-C/sub 4/ olefins and a recycle gas stream containing ethene; means for fractionating C/sub 3//sup +/more » sorbate to provide C/sub 5//sup +/ gasoline and a C/sub 3/-C/sub 4/ olefin stream; second reactor means for reacting the C/sub 3/-C/sub 4/ olefin stream from fractionation means with excess C/sub 4/-C/sub 5/ isoparaffin in a secondary alkylation stage with liquid phase acid catalyst to convert at least a portion of C/sub 3/-C/sub 4/ olefins to a heavier C/sub 7//sup +/ liquid hydrocarbon.« less
