And a method of manufacturing the catalyst used in the synthesis of oxalate by CO coupling reaction

摘要

Respect to catalyst used in the synthesis of oxalate by CO coupling reaction is the catalyst, and a skeleton with a wire mesh, the carrier coating layer is applied to the surface of the gold network, the present invention is co-active ingredient on the surface of the carrier-coating layer catalyst is supported. Compared to the prior art, the premise under the catalytic activity retention equivalent, the present invention is able to significantly reduce the amount of the noble metal active component in a unit volume of catalyst; clearly reduced the pressure loss of the layer bed catalyst it is possible to be able to effectively reduce the temperature difference in the radial direction of the layer-bed catalyst, to improve the heat transfer problems of the course of the reaction; be can be honeycomb conventional catalysts are applied in the reaction scheme I was able to solve the problem that the temperature runaway is likely to occur during that.
