Selection and Research of Catalysts for Start-up of Catalytic Cracking Units
The catalytic cracking unit has multiple process flows and a long start-up time.Choosing a suitable start-up catalyst is an important part of ensuring the smooth start-up and production of the catalytic cracking unit.In this article,the selection of fresh or equilibrium catalysts for start-up catalysts was analyzed,and the widely used equilibrium catalyst currently in operation was further studied.The sources and properties of start-up equilibrium catalyst were introduced,and suggestions for important indicators such as MAT,SA,metal,and particle size distribution of start-up equilibrium catalyst were put forward to guide and assist equipment start-up personnel in better selecting start-up equilibrium catalyst.
