Abstract: The catalysts of LDR series adopt a unique composite modification method for Y-shaped and ZSM-5 zeolites. A new-type matrix and catalyst preparation process technology is used to improve the pore structure, acidity and stability of catalyst. This product can effectively solve the contradiction among maximization of propylene, reduction of olefin in gasoline and cracking of heavy oil. This catalyst is characterized for its strong heavy oil cracking ability, high yield of propylene, high gasoline octane number and low olefin content in gasoline. The catalysts of LDR series are applicable for normal FCC units and MIP-CGP FCC units with VGO and mixing feed of residual oil or CGO as feed oil for cleaner gasoline production to improve gasoline octane number and propylene yield.

Key words: catalytic cracking, catalyst, MIP-CGP process, propylene yield, octane number
