Abstract: This invention is a process for the regeneration of a catalyst system component comprising certain transition aluminas promoted with a Lewis acid (preferably BF3) 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.

Abstract: This invention is a process for the regeneration of solid acidic hydrocarbon conversion catalysts, but particularly certain transition aluminas and zeolites promoted with Lewis acids (preferably BF3) which have been used in the alkylation of isoparaffins with olefins. The process involves the removal of some portion of the reaction product residue adhering to the solid catalyst by contact with a solvent to partially recover the catalyst's initial activity.
