Abstract

Internal combustion engines produce a number of emissions including oxides of nitrogen, NOx. One manner of reducing NOx production used in gas turbine engines is through the use of catalytic reactors. Catalytic reactors reduce the ignition temperatures required for complete combustion of a fuel air mixture. However, high temperatures present in catalytic reactors cause sintering of the substrate, vaporization of the catalyst, and sintering of catalyst and metal substrate. The present invention is directed at controlling the temperature of a catalytic reactor in an internal combustion engine. An exothermic catalyst coats a first side of a substrate in the catalytic reactor. An endothermic catalyst coats a second side of the substrate.
