Steady State Isotopic Transient Kinetic Analysis of Flameless Methane Combustion over Pd/Al2O3 and Pt/Al2O3 Catalysts

摘要

The SSITKA measurements were performed in the steady state of complete methane oxidation on the Pd/ Al2O3 and Pt/Al2O3 catalysts. It was found that the number of intermediates and their average life-time on the catalyst surface changes with the increase of reaction temperature. On the Pd/Al2O3 catalyst there is larger number of active centres than on Pt/Al2O3 catalyst which permits the course of methane oxidation at lower temperatures.
