Abstract
This invention is a process for the regeneration of a catalyst system component comprising certain transition aluminas promoted with a Lewis acid (preferably BF.sub.3) which have been used in the alkylation of isoparaffin with olefins. The process involves the calcination of the catalyst system component to volatilize and to oxidize the reaction product residue adhering to the solid catalyst. The process may include recovery and recycle of the involved Lewis acid.
