Abstract
Processes for the catalytic combustion of hydrocarbons, carbon monoxide, hydrogen, or mixtures thereof (processes with one or more catalytic stages) and processes of abating the pollution produced by the exhaust gases of vehicles that run on natural gas using a non-selective oxidation catalyst. The non-selective oxidation catalyst comprises a monolithic substrate, a porous support with a refractory inorganic oxide base and an active phase that consists of cerium, zirconium, iron, and at least one metal that is selected from the group that is formed by palladium and platinum is described; with the porous support content being between 200 and 400 g per liter of catalyst; with the cerium content being between 0.3 and 20% by weight relative to the porous support; with the zirconium content being between 0.3 and 20% by weight relative to the porous support; with the iron content being between 0.01 and 3.5% of iron by weight relative to the porous support; and with the palladium and/or platinum content being higher than 3 g per liter of catalyst.
