The present invention is directed to a process for adsorptive separation of carbon monoxide or olefins from gas mixtures using adsorbents, which comprise cuprous compounds dispersed on amorphous oxide or carbon macroporous supports. The compositions are prepared by impregnating cupric compounds on, preferably pretreated, supports with the aid of an aqueous solution of an ammonium salt of a di- or polycarboxylic acid dispersant, such as ammonium citrate, followed by reduction of the cupric compound to the corresponding cuprous compound. The reduction can ...
A process of selectively separating a gas component selected from the group consisting of carbon monoxide or olefins from a gas mixture containing said gas component and at least one other gas selected from the group consisting of carbon dioxide, methane, nitrogen, hydrogen, argon, helium, ethane and propane, comprising contacting the gas mixture with a cuprous halide-containing adsorbent comprising a high surface area support of amorphous oxide or carbon and a dispersed cuprous halide prepared by impregnating the support with a cupric compound in an aqu...
