RESEARCH PROGRESS ON THE RESOURCE UTILIZATION TECHNOLOGIES OF WASTE FLUID CATALYTIC CRACKING CATALYSTS

Abstract

Abstract: Fluid Catalytic Cracking (FCC) is one of the critical processes in petroleum refining, and the resource utilization of waste FCC catalysts has emerged as a pressing challenge requiring urgent resolution. The sources and formation mechanisms of waste FCC catalysts are systematically reviewed, the key advantages and technical bottlenecks of regeneration and resource utilization technologies are analyzed, and the future research directions and application prospects are discussed. Considering the development trends in resource utilization and harmless treatment of waste catalysts, it is proposed that future efforts should prioritize the development of high-efficiency regeneration technologies, explore green and low-carbon pathways for resource recovery, and strengthen the synergistic integration of cascade regeneration and resource utilization. These strategies aim to achieve large-scale, low-impact, and high-value applications of waste catalysts.

Key words: waste FCC catalyst, resource utilization, harmless treatment, regeneration technology, low-carbon
