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.

Claim (Index 1):
A process for treating spent catalyst from a reaction zone comprising:\n (a) passing the spent catalyst to a sulfur stripping vessel, wherein the spent catalyst comprises at least one sulfur-containing compound; (b) combining a gas stream and a stream comprising a source of oxygen to form a combined stream wherein the combined stream provides oxygen in an amount of from about 1000 mol-ppm oxygen to about 20000 mol-ppm oxygen in the sulfur stripping vessel at sulfur stripping conditions; (c) passing the combined stream to the sulfur stripping vessel at a temperature sufficient to result in the sulfur stripping vessel operating at from about 100\u00b0 C. to about 700\u00b0 C. and contacting oxygen generated from the combined stream with the spent catalyst and generate stripped spent catalyst; (d) passing the stripped spent catalyst to a regenerator to provide a regenerated catalyst; and (e) returning the regenerated catalyst to the reaction zone.
