| 英文摘要 | the effect of iron promoter on the catalytic properties of rh-mn-li/sio2 catalyst in the synthesis of c-2 oxygenates from syngas was investigated by means of the following techniques: co hydrogenation reaction, temperature-programmed reduction (tpr), temperature-programmed desorption and reaction of adsorbed co (co-tpd and tpsr) and pulse adsorption of co. the results showed that the addition of iron promoter could improve the activity of the catalysts. unexpectedly, the yield of c-2 oxygenates increased greatly from 331.6 up to 457.5 g/(kg h) when 0.05% fe was added into rh-mn-li/sio2 catalyst, while no change in the selectivity to c-2 oxygenates was observed. however, the activity and selectivity of c-2 oxygenates were greatly decreased if the fe amount exceeded 1.0%. the existence of a little iron decreased the reducibility of rh precursor, while the reduction of fe component itself became easier. co uptake decreased with increasing the quantity of fe addition. this phenomenon was further confirmed by co-tpd results. the co-tpd and tpsr results showed that only the strongly adsorbed co could be hydrogenated, while the weakly adsorbed co was desorbed. we propose that fe is highly dispersed and in close contact with rh and mn; such arrangements were responsible for the high yield of c-2 oxygenates.
