Abstract
A process for regenerating a spent copper-porous refractory metal oxide carrier composite for sorbing sulfur compounds from hydrocarbons in which the spent sorbent is optionally stripped of hydrocarbons, oxidized to convert absorbed sulfur to a sulfate form, and then purged with an inert gas at temperatures that decompose the sulfate form to sulfur dioxide, thereby reducing the sulfur content of the sorbent substantially.
