The catalyst and method in order to synthesize C2 oxygenation ones with the hydrogenation of carbon monoxide

摘要

It discloses concerning the catalyst for synthesizing C₂ - oxides with the hydrogenation of CO. This catalyst Rh Mn Fe M1 M2/SiO2 and especially Mn Fe M1 and M is formed with₂ and the additive. As for M₁ on the one hand to make Ru or Ir it is possible M where it is possible to make Li or Na,₂. The content of Rh is 0.1 - 3 weight %, the weight ratio of Mn/Rh is 0.5 - 12, the weight ratio of Fe/Rh is 0.01 - 0.5, weight ratio of M₁ /Rh is 0.01 - 1, weight ratio of M₂ /Rh is 0.1 - 1.0. The catalyst is drawn up, dries, at the desire quantity impregnation being able to point to the solution of the corresponding chemical compound of each component to the carrier of SiO_2, at 283 - 473K next. It precedes use, as for the catalyst it is restored after the drying in 2 - 20 hours in 473 - 673K due to the hydrogen or hydrogen content gas at 573 - 673K over 1 hours at least, or after the calcination. These catalysts CO and H_{2 the} ethanol and the acetaldehyde, to acetic acid and other C₂ - oxygenation ones at high conversion rate and high selectivity relief can convert under condition. Selective figure It is not
