Tóm tắt

The dissociation of CH4 and CO2, as well as the reaction between CH4 and CO2 at 723–823 K have been studied over alumina supported Pt metals. In the high temperature interaction of CH4 with catalyst surface small amounts of C2H6 were detected. In the reaction of CH4+CO2, CO and H2 were produced with different ratios. The specific activities of the catalysts decreased in the order: Ru, Pd, Rh, Pt and Ir, which agreed with their activity order towards the dissociation of CO2.
