PROCESS FOR CATALYST REGENERATION

摘要

A process for regenerating used catalyst particles contaminated with carbonaceous and/or sulfur-containing materials, which process comprises the steps of: a) contacting said particles in a fluidized bed with an oxygencontaining gas at an elevated temperature whereby at least part of the contaminants is removed, and b) passing the thus treated catalyst particles to a moving belt and causing the belt to move said catalyst particles through a furnace zone, which is maintained at a temperature sufficient to remove the remaining portion of the contaminants from the catalyst particles.
