Abstract
Novel adsorbents for use in the separation of carbon monoxide and/or unsaturated hydrocarbons from mixed gases. An adsorbent for separating carbon monoxide or unsaturated hydrocarbon from mixed gases is made by heating a solid mixture comprising a copper compound and a support having a high surface area in a suitable atmosphere.
Claims62
An adsorbent for use in selective adsorption of CO, unsaturated hydrocarbons, or mixtures thereof, from a mixed gas, comprising:
- (i) a suitable support having a sufficiently high surface area, and (ii) a cuprous compound on said support prepared by heating a solid mixture of said support and copper compound selected from the group consisting of a cuprous compound, a cupric compound and combinations thereof at a temperature and for a time period sufficient to disperse an adsorbent effective amount of said copper compound onto the surface of said support.
An adsorbent for use in selective adsorption of CO, unsaturated hydrocarbons, or mixtures thereof, from a mixed gas, which comprises (i) a suitable support having a sufficiently high surface area, and (ii) a cuprous compound which is supported by said support and is prepared by a process comprising the step of heating a mixture of said support and a copper compound selected from the group consisting of a cuprous compound, a cupric compound and a combination thereof at a temperature in the range from about 300.degree. C. to about 800.degree. C. and for a period of time sufficient to disperse an adsorbent effective amount of said copper compound onto the surface of said support to produce an active adsorbent.
An adsorbent for use in selective adsorption of CO, unsaturated hydrocarbons, or mixtures thereof, from a mixed gas which adsorbent comprises (i) a suitable support selected from the group consisting of a zeolite, an alumina, a silica gel, an aluminosilicate, a porous aluminum phosphate, and combinations thereof, and (ii) a cuprous compound which is supported by said support, said adsorbent being obtained by a process comprising the steps of (A) removing the solvent from a mixture containing said copper compounds, said support and a suitable solvent to produce a solid mixture, and (B) heating said solid mixture at a temperature and for a period of time sufficient to disperse an adsorbent effective amount of said copper compound onto the surface of said support to produce an active adsorbent.
A process of preparing an adsorbent for use in selective adsorption of CO, unsaturated hydrocarbons, or mixtures thereof, from a mixed gas, which adsorbent comprises (i) a suitable support having a sufficiently high surface area, and (ii) a cuprous compound which is supported by said support, which process comprises the step of heating a mixture of said support and a copper compound selected from the group consisting of a cuprous compound, a cupric compound, and a combination thereof, at a temperature in the range from about 300.degree. C. to about 800.degree. C. and for a period of time sufficient to disperse an adsorbent effective amount of said copper compound onto the surface of said support to produce an active adsorbent.
A process of preparing an adsorbent for use in selective adsorption of CO, unsaturated hydrocarbons, or mixtures thereof, from a mixed gas, which adsorbent comprises (i) a suitable support having a sufficiently high surface area, and (ii) a cuprous compound which is supported by said support, which process comprises the step of heating a solid mixture of said support and a copper compound selected from the group consisting of a cuprous compound, a cupric compound, and a combination thereof, at a temperature and for a period of time sufficient to disperse an adsorbent effective amount of said copper compound onto the surface of said support to produce an active adsorbent.
