摘要： The present invention relates to an adsorbent for separating carbon monoxide from a gas mixture including hydrogen gas and a method of preparing the same. The adsorbent for selectively separating monoxide includes a solid material, which is a solid support impregnated and dispersed with a cuprous salt by bringing the solid support into contact with a cuprous salt solution stabilized by dissolving a cuprous salt or a cuprous salt mixture in a solvent. The adsorbent is advantageous in that the selectivity for carbon monoxide is improved, so that the amount of carbon monoxide included in the gas mixture is decreased to infinitesimal quantities, thereby producing high-purity hydrogen products.

摘要： A group of solid adsorbents in the form of powder, granules or pellets having improved adsorptive capacity and selectivity for ethylene and/or propylene is disclosed. These adsorbents comprise (a) a silver compound and (b) a bentonite clay support bulk of which comprises SiO2 and Al2O3 and the rest being oxides of Fe, Ca, Mg, Na and K and having sufficiently high surface area on which the silver compound is dispersed or impregnated. The support may be pretreated by polymer solutions to impart sufficient mechanical strength as measured by attrition loss. Mechanical strength may also be improved by pre-heating the support. These adsorbents are highly stable and are capable of reversibly adsorbing substantial quantity of ethylene and/or propylene at room temperature. The rates of adsorption of ethylene and/or propylene are also very high in these adsorbents, which is believed to be due to the synergistic interaction between the components of the novel composition of the present invention.

摘要： Disclosed are a pressure swing adsorption apparatus for hydrogen purification and a hydrogen purification method using the same. The pressure swing adsorption apparatus for hydrogen purification includes a plurality of adsorption columns connected with a feed supply pipe, a hydrogen storage tank for collecting purified hydrogen from the adsorption columns, and valves for opening or closing a plurality of pipes connected to the respective adsorption columns, and the adsorption columns are packed with adsorbent beds of active alumina or silica gel, activated carbon, zeolite 13X, zeolite 5A, and a carbon monoxide-selective adsorbent other than the zeolite 5A, in order to remove carbon dioxide, methane, and carbon monoxide from a hydrogen-containing gas mixture supplied through the feed supply pipe, and the content of carbon monoxide in the discharged hydrogen is minimized through sequential adsorption on the adsorbents in the adsorption columns. The content of carbon monoxide in the purified hydrogen product can be decreased to 10 ppm or less, thus facilitating the production of highly pure hydrogen products.
