Abstract: Catalysis technology is an irreplaceable key technology that promotes the development of modern industry. In modern industries such as petroleum, chemical, biochemical, and environmental protection, over 90% of industrial processes are related to catalysis technology and involve the application of catalysts. The catalyst plant of the PetroChina Lanzhou Petrochemical Company(referred as LPC) was completed and put into operation in 1964. It was the first petroleum processing catalyst production plant in China, where the small ball catalyst, one of the "Five Golden Flowers" of the petroleum front, was born. It is known as the cradle of catalytic cracking catalysts in China.In the development process of more than 60 years, LPC's catalyst business has always focused on the major needs of national energy security and green low-carbon development. It has always inherited Daqing and iron man spirit, and has developed 4 series and 40 varieties of catalysts.All research and development achievements have been industrialized, also providing key core technologies for building the world's largest single catalyst production device capacity and creating a completely independent and controllable catalyst industry chain.
