Abstract: The present invention relates to a process for preparing fluid catalytic cracking (FCC) catalysts having porosity and accessibility controlled by the activity of water-soluble porogens. The catalyst produced can be used as an additive for fluid cracking, as additives for SOx and NOx reduction, as a combustion promoter and reduction of sulfur in cracked naphtha. It can also be used in hydrocracking, as a support for hydrotreating catalysts, catalytic pyrolysis of post-consumer polymers (rubber tires, plastic films, and so on) and pyrolysis of biomass.
