    摘要： Described is a process of catalytic combustion with staged fuel injection that comprises: a first injection of fuel and air, the passage of the air-fuel mixture that is formed into a catalytic zone, and a second fuel injection into the flow of output from said catalytic zone; with said process being characterized in that said catalytic zone comprises at least one catalyst that comprises a monolithic substrate, a porous support based on a refractory inorganic oxide, and an active phase that comprises cerium, iron, and optionally zirconium, as well as at least one metal that is selected from the group that is formed by palladium and platinum; the content of porous support is between 100 and 400 g per liter of catalyst; the cerium content is between 0.3 and 20% by weight relative to the porous support; the zirconium content is between 0 and 20% by weight relative to the porous support; with the iron content being between 0.01 and 3.5% by weight of iron relative to the porous support; and the palladium and/or platinum content is greater than 3 g per liter of catalyst. The process that uses such a catalyst produces improved performance levels by avoiding the fluctuating nature of combustion and the deactivation of the catalyst.
