ABSTRACT:
The deactivated fluorosulfuric acid catalyst in olefin-paraffin alkylation is regenerated by (1) contacting the acid phase with water to form an acid-water mixture (2) stripping the acid-water mixture with a paraffin to form a gaseous phase of hydrogen fluoride and paraffin (3) cooling the gaseous phase with liquid paraffin to form a liquid fluorosulfuric acid and a vapor containing fluorosulfuric acid, hydrogen fluoride and paraffin (4) treating the vapor with liquid SO.sub.3, and utilizing liquid fluorosulfuric acid in the treating step in countercurrent flow to the vapor to convert the hydrogen fluoride to regenerated fluorosulfuric acid, (5) the remaining gas phase containing paraffin and a minor amount of fluorosulfuric acid is cooled to condense all the fluorosulfuric acid to liquid and (6) the regenerated liquid fluorosulfuric acid is used as the countercurrent flowing liquid fluorosulfuric acid in treating step (4).
