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 similar to 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.
