摘要： 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.
