Abstract: The development history and the latest advancements in fluid catalytic cracking (FCC) catalyst production technology in China are primarily introduced. Since the establishment of China's first FCC unit in 1965, domestic FCC catalyst production technology has undergone continuous innovation, gradually forming a series of products that can meet domestic market demands and have been exported to multiple countries. The key directions of FCC catalyst production technology are highlighted: enhancing yield, optimizing performance, achieving clean production, and enabling resource utilization.Through technological innovation and equipment upgrades, catalyst production has achieved large-scale, continuous, automated, and cleaner operations. The capacity of single-unit installations has increased from 5 kt/a to 50 kt/a, reaching internationally advanced levels. Specific technologies include zeolite mother liquor recycling, continuous production processes, low-temperature spray drying, and high-temperature calcination, which have significantly improved catalyst yield and performance. Concurrently, the application of environmental protection technologies has enabled effective treatment of exhaust gases, wastewater, and solid waste generated during production, realizing green manufacturing practices.Future efforts will continue to focus on cleaner production, intelligent manufacturing, and specialized catalyst development to support the high-quality and sustainable growth of the refining industry.
