Abstract
A process is presented for the treatment of spent catalyst to manage sulfur-containing compounds on the catalyst. The catalyst may be a dehydrogenation catalyst, where sulfur accumulates during a dehydrogenation process. Sulfur compounds are stripped from the spent catalyst and the catalyst may be cooled before a regeneration step. The process includes controlling removal of sulfur compounds from the spent catalyst before regeneration.
