Catalytic combustion for equivalence ratios between 0.7 and 1.6 was investigated. The combustor consisted of a 5-cm-diameter monolithic Corderite substrate with a γ-alumina washcoat and platinum coating. Reactants were propane/oxygen/argon mixtures. Trace amounts of either nitric oxide or ammonia were added for the fuel-nitrogen portion of the study. Conversion of these two model fuel-nitrogen compounds to nitric oxide was measured as a function of equivalence ratio, adiabatic flame temperature, and fuel nitrogen concentration. The trends were compared to those typical of homogeneous combustion. Use of oxygen/argon mixtures as the oxidizer allowed decoupling of the flame temperature and equivalence ratio and made possible investigation of catalytic combustion under stoichiometric conditions which would not be possible with a fuel/air mixture because of material limitations. Catalyst temperatures, combustion efficiency, and emissions of CO, CO2, and UHC's were investigated.
