Diffusive catalytic combustion burner. (III).

Journal of the Fuel Society of Japan, 1988
Kinetic studies of methane in a microreactor were carried out to clarify the reaction mechanism of a diffusive catalytic combustion burner for city gas using a combustion catalyst composed of porous alumina fibers impregnated with rhodium. Fresh catalysts, H2S treated catalysts and life test catalysts were all tested in oxidation, steam reforming and ...
