Abstract: An adsorber for selectively separating a carbon monoxide is provided to produce hydrogen product having high purity in which an including ingredient of the carbon monoxide in the mixed gas is lowed extremely little. An adsorber for selectively separating a carbon monoxide is manufactured by impregnating and dispersing the cuprous salt into the solid support by dissolving a cuprous salt or a mixture of the cuprous salt in a predetermined solvent and contacting a solid support into a stabilized cuprous salt solution. The cuprous salt is one of a cuprous salt of a cuprous halide and a cuprous salt of a cuprous acetate or a mixture thereof.

Abstract: An olefin selective adsorbent using copper-based complex metal chloride is provided to manufacture an adsorbent showing the quantity of adsorbed olefin and selectivity equal to those of a silver-ion impregnated adsorbent. An olefin selective adsorbent is an adsorbent for absorbing/separating olefin from olefin/paraffin compound. Ferric chloride(FeCl2) of 5 through 29.9 wt% and cupric chloride(CuCl) of 5 through 23.4wt% are dipped into a substrate in which specific surface area is 100 m^2/g or greater. The substrate having large specific surface area is selected from MCM-41, MCM-48, SBA-15, SBA-16 and KIT-6 which are aluminosilica gel, silica gel, alumina and middle-sized porous silica.

Abstract: A method and an apparatus for enrichment of ethylene from FCC(Fluid Catalytic Cracking) off-gas are provided to treat a large volume of off-gas by desorbing and recovering the ethylene using a desorbent after adsorbing ethylene onto an olefin selective adsorbent, and to protect an adsorbent used in the enrichment of ethylene by removing water contained in the off-gas through a pre-treatment adsorption process. A method for separating ethylene from FCC off-gas comprises: a pre-treatment process including an adsorption step of introducing FCC off-gas to adsorb water and a desorption step of introducing an ethylene removing stream exhausted from the ethylene separation process to clean and desorb the adsorbed water; and an ethylene adsorbing and separating process including an adsorption step of introducing the pre-treated FCC off-gas into an adsorption tower to adsorb ethylene, and sending non-adsorbed components and an adsorbent in the adsorption tower to a distillation tower for separating the ethylene removing stream and an adsorbent, an ethylene cleaning step of introducing a portion of high concentration olefin obtained from an ethylene enriched stream/desorbent distillation tower into the adsorption tower to increase the purity of ethylene, and a desorption step of introducing a desorbent into the adsorption tower to desorb ethylene and sending the desorbed ethylene to a distillation tower for separating a mixture of the ethylene enriched stream and the desorbent to produce an ethylene enriched stream.
