Abstract |
Kinetic analysis by direct curve fitting was performed on catalytic combustion of methane over Mn-substituted hexaaluminates. The analysis provided useful information in understanding the complicated ...interaction among the surface catalyzed reaction, the mass transfer process, and the gas phase reaction. The large surface area catalyst is effective in promoting the combustion reaction under the limitation of mass transfer. At higher temperatures, strong interaction between surface catalyzed and gas phase reactions takes place because the thermal formation of radical species, which are necessary for the initiation of gas phase reactions, is suppressed by the surface catalyzed oxidation.show more
