FCC catalyst for two-stage catalytic cracking or MIP process
fcc@fcccatalyst.net
It is suitable for two-stage catalytic cracking device and MIP process device. It adopts highly active rare earth Y molecular sieve and P-ZSM-5 molecular sieve, as well as molecular sieve and catalyst pore expanding technology, and is suitable for catalytic cracking of residue oil. The catalyst has a strong ability to crack heavy oil, higher cracking activity, lower coke yield and stronger ability to resist metal pollution, while producing more low-carbon olefins, high liquefied gas yield and gasoline yield, so widen It has a range of applications.
Performance characteristics:
- Molecular sieve with multiple active combinations to ensure excellent coke selectivity and durability of activity.
- The ultra-stable Y-type molecular sieve active components are specially treated to increase the number of mesopores to meet the needs of heavy oil macromolecules.
- Adopting activated alumina improvement technology and pore expansion technology effectively improves the ability of the carrier to crack macromolecules.
- Adjust active components to enhance resistance to heavy metal pollution
