ABSTRACT:
Used catalyst containing carbon and sulfur deposits is continuously regenerated by staged burnoff of the carbon and sulfur using a multiple zone treatment vessel containing thin beds of catalyst. The catalyst is exposed to successively increased temperatures and oxygen concentrations to effectively remove substantially all the carbon and sulfur deposits. The used catalyst can be that removed from hydroconversion processes, such as from H-Oil, H-Coal and fluid catalystic cracking processes, and processed in a multizone treatment vessel in combination with proper auxiliary heating equipment for continuous step-wise regeneration of the catalyst. Operating conditions of catalyst temperature, oxygen concentration of gas, and catalyst residence time in each stage of the catalyst regeneration process are carefully controlled to provide staged burnoff of carbon and sulfur deposits for superior regenerated catalyst results. The hot regenerated catalyst withdrawn from the last zone is cooled against make-up air to improve the overall thermal efficiency of the process.
