A Kinetic Study of Selective Hydrogenation of Carbon Monoxide to C2 Oxygenates on Rh-Mn-Li-Fe／SiO2 Catalyst

The kinetics of CO hydrogenation for the synthesis of C2 oxygenates over Rh-Mn-Li-Fe/SiO2was investigated. Kinetic parameters for the formation of ethanol, acetaldehyde, C2 oxygenates, methanol and methane were obtained. The activation energy, H2 and CO dependence orders for ethanol and acetaldehyde formation differed greatly, the large difference seemed to imply that they were formed through different intermediates.
