Abstract: Catalytic cracking process is the core process of secondary processing in petroleum refining. Starting from the global catalytic cracking capacity and China's catalytic cracking capacity, this article summarizes the status and role of catalytic cracking technology in petroleum processing, with a focus on analyzing the changes in the cracking capacity of fluid catalytic cracking (FCC) in refineries. Taking statistical data from some units as an example, it elaborates on the versatility and adaptability of its processing materials. Summarized the contributions made by FCC's main products such as gasoline, diesel, liquefied gas, and slurry to the development of China's transportation and petrochemical industries.

Key words: catalytic cracking, capacity, gasoline, diesel, propylene
