Cracking catalyst composition

摘要

The present invention relates to a cracking catalyst composition comprising a physical mixture of 10-90 weight % of a cracking catalyst A and 90-10 weight % of a cracking catalyst B, whereby catalyst A is a zeolite-containing cracking catalyst, and catalyst B is a catalyst having a higher average pore volume in the pore diameter range of 20-200 Å than catalyst A in the same pore diameter range and not containing M41S material. These compositions can suitably used for the fluid catalytic cracking of hydrocarbon feeds with high metal concentrations.
