System for conversion of crude oxygenate to gasoline with feedstock extraction
This patent describes a continuous feedstock extractions and reactor system for converting crude oxygenated hydrocarbon feedstock to gasoline boiling range hydrocarbons. It comprises: extractor means for contacting oxygenate liquid containing a minor amount of water with a liquid hydrocarbon extraction stream under extraction conditions favorable to selective extractions of oxygenate, thereby providing an extract liquid stream rich in oxygenate and an aqueous raffinate stream lean in oxygenate; catalytic reactor means for contacting at least a portion of the extract stream in a catalyst reaction zone with conversion catalyst under process conditions to convert substantially all oxygenate to hydrocarbons; separation means for receiving reactor effluent to recover an aqueous liquid byproduct stream, a gaseous stream rich in C/sub 2/ - hydrocarbons, a liquid product stream comprising C/sub 5//sup +/ liquid hydrocarbons, and a liquid stream rich in C/sub 3/-C/sub 4/ hydrocarbons; means for recycling at least a portion of at least one liquid phase to extractor means for use as extraction liquid.
