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.

The present invention relates to HTS catalysts applied in hydrogen or synthesis gas production units, whether in steam reforming, autothermal reforming, dry or gasification reforming, chromium-free, consisting of iron oxide, containing platinum contents between 0.1 to 0.4% w/w, promoted by sodium contents between 0.1 to 0.3% w/w, and optionally aluminum contents between 5.0 to 6.0% w/w inserted into the crystal lattice of an iron oxide with a hematite (Fe.sub.2O.sub.3) crystal structure, thus, allowing high activity to be reconciled with excellent resistance to deactivation by exposure to high temperatures. In a second aspect, the present invention provides a carbon monoxide conversion process by bringing said catalyst into contact with a synthesis gas stream, where the maximum bed temperature can be limited by the injection of water or steam next to the feed of CO-containing gas at the reactor inlet.
