<p>PURPOSE:To eliminate the clogging of an absorbent packed part at the time of the passage of dust-containing gas, by forming a carbon monoxide absorbent by using copper halide and activated carbon as constitutional components and molding both components into a monolithic shape. CONSTITUTION:A monolithic shape molded body containing activated carbon as a constitutional component and having gas flow channels (a) is immersed in a solvent containing copper halide. Next, said solvent is stirred and subsequently removed by vacuum distillation to obtain a carbon monoxide adsorbent. The compounding ratio of activated carbon to copper halide is about 1-30, pref., about 3-5 on a wt. ratio basis. As copper halide, there are copper (I) chloride, copper (I) fluoride, copper (I) bromide, copper (II) chloride, copper (II) fluoride or copper (II) bromide. As the solvent, water, an aqueous hydrochloric acid solution, benzene, toluene, propionitryle or acetonitryle are used.</p> |
