Solid adsorbent for unsaturated hydrocarbon and process for separation of unsaturated hydrocarbon from gas mixture.

摘要

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°C to 140°C under normal pressures.
