Abstract: Deactivated catalysts containing Group VIII metal contact agents are regenerated by a process comprising impregnating the deactivated composite material with tin or a tin compound. Preferably, the tin-impregnated composite is thereafter calcined. The process is particularly suitable for the regeneration of deactivated reforming and dehydrogenation catalysts.
