Project Description
Special Catalyst For MIP-CGP Process FCC catalyst
Applicable Scope：
Specially formulated catalyst for MIP-CGP process.
Characteristics
CGP series catalyst is developed for MIP-CGP Process, which has high propylene and gasoline yields, excellent gasoline properties, good hydrothermal stability, high bottom conversion ability, and good coke selectivity.
Design Philosophy
CGP series catalyst was developed to meet the requirements of MIP-CGP process, to get higher hydrogen transfer activity and gasoline olefins cracking activity. catalyst CGP is characterized in: firstly, coke is Shifted to the matrix by the CS technology, thus hydrogen transfer activity in the second reaction zone enhanced; secondly, the gasoline olefins can be selectively cracked by RIPP proprietary shape selective zeolite, making gasoline olefins reduced and propylene yield increased.
