▎ 摘　　要

NOVELTY - Highly dispersing carbon monoxide adsorbent comprises using auxiliary agent, carrier and active component loaded on the carrier. The auxiliary agent is cerium, the carrier is porous carbon carrier, and the active component is copper (I). USE - The adsorbent is useful for deeply removing trace carbon monoxide in hydrogen to meet the requirements of hydrogen for fuel cell vehicles. ADVANTAGE - The adsorbent: can make the active component copper (I) better dispersed on the surface of the porous carbon carrier; can utilize copper (I); and has high carbon monoxide adsorption capacity, high carbon monoxide removal depth. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing the highly dispersed carbon monoxide adsorbent, comprising (1) providing solution containing divalent copper salt and divalent cerium salt, and (2) impregnating the porous carbon carrier with the solution, and calcining under inert atmosphere, where the divalent copper salt is copper chloride; and carbon monoxide adsorption method, comprising contacting carbon monoxide-containing gas with sorbent to adsorb carbon monoxide contained in the gas on the sorbent.
