Abstract: 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 (Fe2O3) 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.

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.

Abstract: [Task] The task is to improve, in the hydrogenation of an aromatic halonitro compound, the yield of halogenated aromatic amine as a target product without the need for a dehalogenation inhibitor while suppressing the production of a nitroso compound.
[Solution] A hydrogenation catalyst for hydrogenation of an aromatic halonitro compound includes: a carrier containing at least one of silica, titania, and alumina; and at least one metal carried by the carrier and selected from group 10 elements in a periodic table.-
