A CATALYST AND PROCESS FOR THE SYNTHESIS OF C2-OXYGENATES BY THE HYDROGENATION OF CARBON MONOXIDE |
摘要 |
A catalyst is invented for the synthesis of C<SUB>2</SUB>-oxygenates by the hydrogenation of CO. The catalyst is composed of Rh-Mn-Fe-M<SUB>1</SUB>- M<SUB>2</SUB>/Si0<SUB>2</SUB>, among them Mn, Fe, M<SUB>1</SUB> and M<SUB>2</SUB> and additives. M<SUB>1</SUB> can be Li or Na while M<SUB>2</SUB> 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 M<SUB>1</SUB>/Rh is 0.01-1 and the weight ratio of M<SUB>2</SUB>/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 Si0<SUB>2</SUB>, 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 2-20h. These catalysts can convert CO and H<SUB>2</SUB> into ethanol, acetaldehyde, acetic acid and other C<SUB>2</SUB>-oxygenates at a high conversion and a high selectivity under mild conditions. |
