Abstract
A process for the regeneration of a sulfur containing catalysts, wherein the catalyst is stripped of sulfur before the oxychlorination treatment of the regeneration process, typically before the catalyst is sent to the regeneration zone. The process is particularly useful for catalyst employed in hydrocarbon conversions such as dehydrogenation reactions, particularly those which comprise the injection of sulfur and/or at least one sulfur compound before or simultaneously to the introduction of the charge into the first reaction zone.
