ABSTRACT:
A process for the alkylation of alkanes with olefins under alkylation conditions employing a regenerated catalyst having improved activity. The regenerated catalyst is prepared by contacting a deactivated chlorided alumina catalyst in a non-oxidizing atmosphere at a temperature between 400.degree. and 1200.degree. F., thereafter contacting said catalyst in an oxidizing atmosphere at a temperature between 700.degree. and 1200.degree. F. and subsequently rechloriding said catalyst at a temperature between 200.degree. and 800.degree. F.
