Catalytic Cracking Catalyst(DCC Process)

The catalytic cracking catalyst used in the DCC process takes heavy oil as raw material, uses solid acid shape-selective molecular sieve catalyst, and conducts cracking reaction under mild reaction conditions to produce low-carbon olefins or isomerized olefins and high-octane gasoline. .

The process draws on the fluidized catalytic cracking technology and adopts the fluidization, continuous reaction and regeneration technology of the catalyst.

For zeolite molecular sieve cracking catalysts, the pore structure, acidity and grain size of molecular sieves are the three most important factors affecting the catalytic effect; for metal oxide cracking catalysts, the active components, supports and promoters of the catalyst are the most important factors affecting the catalytic effect. the most important factor.
