Abstract
A combustion catalyst comprising a monolithic substrate, a porous support based on refractory inorganic oxide and an active phase formed by cerium, iron and at least one metal selected from the group formed by palladium and platinum, the content of porous support being between 100 and 400 g per liter of catalyst; the content of cerium being between 0.3 and 20% by weight with respect to the porous support; the content of iron being between 0.01 and 3.5% of iron by weight with respect to the porous support; and the content of palladium and/or platinum being between 3 and 20 g per liter of catalyst. The catalyst of the invention is used in particular in processes for the catalytic combustion of hydrocarbons, carbon monoxide, hydrogen or mixtures thereof, in processes involving one or more catalytic stages.
