• Catalytic partial oxidation of methane was studied in adiabatic reactor.
• We examine four catalysts in POX processes of various methane/air mixtures.
• Similar characteristic residence time ∼0.05 s is revealed for all catalysts.
• Composition of measured POX products was compared with developed model predictions.
• Measurements and modeling agree at temperature close to measured at catalyst outlet.
In the experimental setup designed for catalysts testing and development of technological modes, experiments on partial oxidation were carried out using four types of catalysts in the range of equivalence ratios from 2.2 to 6. The characteristic residence time of working mixture in the catalyst unit is ∼0.05 s. The processing of experimental data indicates that the yield compositions may be explained by the radial temperature profile in the catalyst. For all the tested catalysts the measured yield composition is well approximated by averaging the isothermal equilibrium compositions calculated using the suggested temperature profile.
