Abstract
A combination process for production of HF alkylate motor fuel and HF alkylate solvent wherein the alkyl fluoride impurities present in the produced motor fuel are removed therefrom by treatment with a relatively clean HF stream (emulsion) containing the produced HF alkylate solvent. Makeup, relatively clean, HF catalyst for the motor fuel alkylation is secured from the solvent HF alkylate alkylation system. The invention produces motor fuel alkylate substantially free of organic fluoride contaminates as well as substantially organic fluoride-free isoparaffin solvent alkylate, using only one HF rerun column.
