| 英文摘要 | in-situ ft-ir technique was employed to investigate co adsorption and the changes of adsorbed species on the surface of rh-based catalysts during co hydrogenation. the result showed that only the linear co was observed on rh/sio2, while linear co and twin co appeared on rh-mn-li-fe/sio2, indicating that rh dispersion on rh-mn-li-fe/sio2 was higher than that on rh/sio2. in the ir spectra of co hydrogenation under the conditions of 593 k and 3.0 mpa, the bands at 1 716, 1566, 1442, and 1 343 cm which were attributed to c-2 oxygenate precursors, were observed for rh-mn-li-fe/sio2, while no band was detected for rh/sio2. co was adsorbed mainly as linear co on both the catalysts during co hydrogenation. correlating the ftir results with the co hydrogenation performance suggested that the linear co might be mainly responsible for the formation of c-2 oxygenates. the high activity of rh-mn-li-fe/sio2 was due to the fact that the existence of promoters weakened the c-o bond of adsorbed co on the catalyst, promoted co activation and favored the formation of c-2-oxygenate intermediates under the reaction conditions. |
