초록

The present invention is directed to a composition, its synthesis and a process for adsorptive separation of carbon monoxide from gas mixtures using adsorbents, which comprise cuprous compounds on amorphous oxide macroporous supports. The compositions are prepared by impregnating cupric compounds on supports followed by reduction of the cupric compound to the corresponding cuprous compound. The reduction can be performed by the use of a reducing gas, preferably synthesis gas at relatively low temperatures up to 150°C., preferably preceded by the use of e...
