KINETICS AND PRODUCTS OF METHANE OXIDATION IN THE PDSO4-H2SO4 SIO2 SYSTEM AT 220-DEGREES-C/

It has been shown that palladium sulfate, supported along with sulfuri c acid on silica gel (PdSO4 - H2SO4/SiO2), oxidizes methane at 220-deg rees-C with the formation of CO2; and at the same time, H2SO4 is reduc ed to SO2. The yield of CO2 is 25%, SO2 50% (mole) relative to the met hane reacted. When samples of the gas phase of the reactor in the cour se of the experiment, and samples of the PdSO4-H2SO4/SiO2 catalyst aft er complete conversion of CH4, are treated with hydrochloric acid, met hyl chloride is detected; this may be evidence of the formation of met hyl-containing products. Kinetic studies have been made of the consump tion of CH4 and the accumulation of CO2 and SO2, as well as the substr ate selectivity of oxidation of CD4, C2H6, n-C4H10, iso-C4H10, cyclo-C 5H10, CyClo-C6H12, Cyclo-C6D12, CH3OH, and CH3Cl.
