Solid absorbent for unsaturated hydrocarbon and process for separation of unsaturated hydrocarbon from gas mixture

摘要

A solid adsorbent for an unsaturated hydrocarbon including (a) (i) a copper(I) halide or oxide or (ii) a halide, carboxylate, sulfate, basic salt, oxide, or amine complex salt of copper(II) and (b) activated carbon or graphite is described. This solid adsorbent can effectively adsorb an unsaturated hydrocarbon such as ethylene from a gas mixture by being placed in contact with the gas mixture at a temperature of -40 DEG C. to 90 DEG C. under normal pressure.
