The catalyst is composed of Rh-Mn-Fe-M1-M2/Si02, among them Mn, Fe, M1 and M2 and additives. M1 can be Li or Na while M2 can be Ru or Ir. The content of Rh is 0.1-3% by weight; the weight ratio of Mn/Rh is 0.5-12, the weight ratio of Fe/Rh is 0.01-0.5, the weight ratio of M1/Rh is 0.01-1 and the weight ratio of M2/Rh is 0.1-1.0. The catalyst is prepared by impregnation of the solution of corresponding compounds of each component in desired amount onto the carrier of Si02, which is followed by drying at 283-473 K. Before using, the catalyst is reduced by hydrogen or hydrogen-containing gas at 573-673 K for at least one hour after drying or after calcinations at 473-673 K for 2-20 h. These catalysts can convert CO and H2 into ethanol, acetaldehyde, acetic acid and other C2-oxygenates at a high conversion and a high selectivity under mild conditions. |
