Abstract
A process for alkylating isoparaffin hydrocarbon with olefin hydrocarbon in the presence of a sulfuric acid alkylation catalyst wherein hydrocarbon effluent from an alkylation reaction zone is treated in the liquid phase with bauxite or similar adsorbent for removing acid alkyl sulfates, neutral alkyl sulfate and other corrosive species, wherein treated alkylation effluent is flashed at reduced pressure in indirect heat exchange contact with alkylation reaction mixture in said alkylation reaction zone for refrigerating said reaction mixture, and wherein flashed vapors and unflashed liquid are fractionated for recovery of isoparaffin recycle and alkylated hydrocarbon product.
