The partial oxidation of methane (POM) to synthesis gas over SiO2-supported Rh and Ru catalysts was studied by in situ microprobe Raman and in situ time-resolved FTIR (TR-FTIR) spectroscopies. The results of in situ microprobe Raman spectroscopic characterization indicated that no Raman band of Rh2O3 was detected at 500 °C over the Rh/SiO2 catalyst under a flow of a CH4/O2/Ar (2/1/45, molar ratio)...
In situ time-resolved FTIR spectroscopy was used to study the reaction mechanism of partial oxidation of methane to synthesis gas and the interaction of CH 4 /O 2 /He (2/1/45) gas mixture with adsorbed CO species over SiO 2 and γ-Al 2 O 3 supported Rh and Ru catalysts at 500-600 o C. It was found that CO is the primary product for the reaction of CH...
