摘要/Abstract

摘要： The kinetics of CO hydrogenation for the synthesis of C2 oxygenates over Rh-Mn-Li-Fe/SiO2 was 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 diered greatly, the large dierence seemed to imply that they were formed through dierent intermediates.
