Process for catalyst regeneration |
摘要 |
A process for regenerating used catalysts having deposited on their surface contaminants comprising carbonaceous and/or sulfur-containing materials which comprises: a) contacting said particles in a fluidized bed with an oxygen-containing gas at an elevated temperature for a time which does not exceed about twenty minutes wherein at least about fifty percent by weight of the sulfur contaminants are 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 for at least about two hours, wherein said furnace is maintained at a temperature sufficient to remove the remaining portion of the contaminants from the particles. |
