High temperature reactions of carbon surfaces and particles with nitrogen oxides have been actively studied due to their roles in control of soot and nitrogen oxide emissions from diesel engines or solid fuel combustion. For example, N2O production can form in combustion of solid fuels, but its emission can be reduced by reaction with carbon at the high temperatures of interest, and the reaction also oxidizes carbon, helping to remove soot. Because of its positive heat of formation, N2O has been suggested as an oxidant in propulsion systems, with energy released by reaction of N2O with both hydrocarbon fuels and with soot produced in the combustion. From a more fundamental perspective, the kinetics of N2O reactions with various forms of solid carbon have been studied, resulting in a proposed mechanism for reaction of solid carbon surface sites: -C * + N2O (gas) → -C(O) + N2 (gas)
