SELECTIVE DEHYDRATION OF ALCOHOLS TO DIALKYLETHERS AND INTEGRATED ALCOHOL-TO-GASOLINE PROCESSES

摘要

The invention involves an integrated process for converting a C 1 -C4 alcohol to gasoline and/or diesel boiling range product, said process comprising: contacting a C1-C4 alcohol feed under selectively dehydrating conditions with a catalyst comprising gamma- a!umina which is substantial])' free of terminal hydroxy I groups on tetrahedrally coordinated aluminum sites of the catalyst to form a dialkyiether dehydration product; and contacting the dialkyiether dehydration product with a zeolite conversion catalyst under conversion conditions to form the gasoline and/or diesel boiling range hydrocarbon product.
