ABSTRACT:
A solid adsorbent for an unsaturated hydrocarbon comprising (a) (i) a silver or copper(I) halide or (ii) a silver or copper(I) halide and the halide of a bivalent metal, or (iii) a silver or copper(I) halide and an aluminum halide, and (b) polystyrene or a derivative thereof.
This solid adsorbent can effectively adsorb an unsaturated hydrocarbon such as ethylene from a gas mixture by contacting the gas mixture therewith at a temperature of -40.degree. C. to 140.degree. C. under normal pressures.
