Propylene Series Catalyst

Propylene Series Catalyst is the proprietary catalyst for converting heavy fraction into light olefins with the use of shape selective zeolite catalyst. It includes CHP, CRP, CIP, MMC, DMMC, RMMC, OMT and HPE, which have the features of high activity, high conversion capability of heavy oil, good selectivity of light olefins and high strength, etc., and it has been applied in dozens of units around the world.

For example, MMC catalyst adopts multiple active components (such as ZSP zeolite containing phosphor and transition metal) to improve the hydrothermal stability and increase the dehydrogenation function of catalyst. MMC catalyst is also formulated to improve the large molecule cracking ability and heavy metal resistance capability. 

DMMC catalyst is prepared with large pore matrix and new catalysis material, which could produce more propylene and decrease olefin content in gasoline.
