DCC process special catalyst MMC series, DMMC series

Brief introduction of product performance and technical characteristics:

The DCC catalytic cracking process is a new technology developed by the Research Institute of Petrochemical Sciences, which uses heavy distillate oil as raw material, and produces more gaseous olefins under matching catalysts and process technology conditions. MMC series catalysts and DMMC series catalysts are the new technology of this process. The special catalyst has the characteristics of high activity, strong heavy oil conversion capacity, good gas olefin selectivity, and high strength. It has been industrially used in many sets of equipment at home and abroad.

The MMC series catalyst adopts multi-active components mainly composed of ZSP zeolite containing phosphorus and transition metals, which improves the stability of hydrothermal activity of ZSP zeolite, increases the dehydrogenation function of the catalyst for small molecular hydrocarbons, and can further convert alkanes into olefins. , To improve the yield of low-carbon olefins, especially propylene, the catalyst formulation design also enhances the cracking ability of the catalyst macromolecules, and improves the ability of the catalyst to resist heavy metal pollution.

DMMC series catalysts use macroporous substrates and new catalytic materials, and have the technical characteristics of producing more propylene and reducing the content of olefins in gasoline. Its characteristics are as follows:

Develop a new type of macroporous matrix technology to realize the optimal distribution of active components and structural components, and improve the accessibility and availability of active components.

The modified β zeolite and mesoporous materials are used to further improve the combination of main active components and auxiliary active components, improve the distribution of cracked products, and increase the selectivity of low-carbon olefins.

Adjust the ratio of the active components of the catalyst to maximize the production of propylene under the condition of higher reaction temperature in the DCC process; improve the preparation process of the catalyst, increase the stability of the hydrothermal activity of the catalyst, and improve the sphericity of the catalyst.
