Abstract: The research on efficient regeneration technology of fast bed in China has always been accompanied by the development of fluid catalytic cracking technology in China. Based on literature records, this article traces the collaborative development process of China's rapid bed high-efficiency regeneration technology and the development and application of the first set of technology. It elaborates on the development of high-efficiency regeneration processes, especially the achievements made in industrialization technology after the successful development of this technology.

Key words: catalytic cracking, efficient regeneration, fast fluidized bed
