<p><P>PROBLEM TO BE SOLVED: To provide a propylene gas separation/recovery method which can recovery a propylene gas at given high purity from a gas mixture that contains the propylene gas and at least one saturated hydrocarbon gas. <P>SOLUTION: The propylene gas separation/recovery method includes an adsorption step of causing the gas mixture that contains the propylene gas and a propane gas as raw material gas to pass through an adsorption column 1 storing an adsorbent, in which copper(II) chloride as copper(II) halide and sugar as a reducing agent are carried on a support that consists of porous alumina at the same time and reduction-treated, to adsorptively treat at 60°C or more. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
