CGP-1 used in MIP-CGP process exhibits much higher olefins light hydrocarbon cracking activity than that of Cat-A used for regular RFCC process. Pore structure analysis and Ar+ sputtering experiment of CGP-1 indicates that carbon mainly deposits in the mesopores of matrix, which protects the active centers from coke. And it was accorded with the acidity analysis result that more strong acids are reserved in spent CGP-1 than those in Cat-A. This may be the main reason for the improved catalytic property of CGP1 which shows high activity in the second reaction zone for producing clean gasoline and more propylene simultaneously.
