03 Gaseous fuels (derived gaseous fuels) Kinetic test reactions over a temperature range of 723 to 773 K of methane reforming with carbon dioxide was performed over rhodium dispersed on silica, Rh/SiOz, and vanadia-promoted silica, Rh/VOd SiOz. Transmission infrared spectroscopy was applied to obser
Hydrogenation of CO, to ethanol was carried out over Rh/SiO, based catalysts. The main product over the unpromoted catalysts was methane. By adding various metal oxide promoters to the catalysts, CO, conversion and selectivity to alcohols (methanol and ethanol) increased. Among the promoters, Li sal
