英文摘要	CO hydrogenation of Rh + Co/Al2O3 has been studied by using a flow micro-reactor. CO hydrogenation took place over 220 degrees C and reaction activity increased with the reaction temperature and H-2/CO ratio. Coadsorption of CO and H-2 as well as dynamic behavior of coadsorbed CO and H-2 have been investigated by TP-IR dynamic method. The results indicate that in coadsorption of CO and H-2 at 20 degrees C, gem-dicarbonyl CO and linear CO transformed partly into the corresponding carbonyl hydride. With increasing the temperature, the residual gem-dicarbonyl CO and linear CO transformed also into the corresponding carbonyl-hydride, while the carbonyl hydrides transformed into the multi-hydrogen carbonyl hydrides. Before arriving at the reaction temperature, there are only the carbonyl hydrides and the multi-hydrogen carbonyl hydride which led to the formation of CH4 at the reaction temperature on the surface of Rh + Co/Al2O3. To relate these results with the results obtained in CO hydrogenation and in CO disproportionation. We believe that in CO hydrogenation reaction, the scission of C-O bond is via the carbonyl hydride-multihydrogen carbonyl hydride.
