The application of fluidization technology in China's petroleum refining indus try was summerized with fluid catalytic cracking as example. The development and improvement of fluidization technology realized in the type of reactor and regenerator beds, the conveying of fluidized solids, the separation of fluidized solids from gases, the heat transfer in a fluidized bed, and fluidization reaction engineering during the last 20 years were reviewed and illustrated with certain details. At present, the fluidization technology in China is still lagging behind the advanced world level. Extensive research work should be continued in the improvement of contact between gas and solid, reaction engineering, dust recovery,fluidized conveying at high flow rate, test and measurment of industrial fluidized bed, and the wear in fluidized bed and wear-resisting materials, so as to successfully develop a novel fluidization process.
