<p>PURPOSE:To eliminate the clogging of an absorbent packed part, by molding a monolithic shape carbon monoxide absorbent from copper (I) halide, aluminum (III) halide and polystyrene or a polystyrene derivative. CONSTITUTION:Polystyrene or a polystyrene derivative is immersed in a solvent containing copper (I) halide and aluminum (III) halide. Next, stirring is performed for several hr at temp. equal to or less than the b.p. of the solvent and the solvent is subsequently removed under vacuum or by distillation. The impregnated one is further molded into a monolithic shape to obtain a carbon monoxide absorbent having flow channels (a). The polystyrene and the polystyrene derivative are, for example, polystyrene and a polystyrenic resin such as a copolymer consisting of polystyrene and 1-40mol% of divinyl benzene. As copper (I) halide, there are copper (I) chloride, copper (I) fluoride or copper (I) bromide.</p> |
