Document Type and Number:
WIPO Patent Application WO/2021/060289
Kind Code:
A1
Abstract:
Provided are a method for producing a purified gas whereby a phase-transitioning impurity contained in a waste-derived raw material gas can be efficiently removed when generating a valuable material from the raw material gas, a method for producing a valuable material, a gas purification device, and a device for producing a valuable material. A method for producing a purified gas, comprising removing an impurity from a waste-derived raw material gas, the method for producing a purified gas including a solid-phased impurity removal step S11 for passing the raw material gas through a phase-transitioning-impurity removal unit to remove a solid-phased phase-transitioning impurity in the raw material gas, and an impurity removal step S12 for passing the raw material gas that has undergone the solid-phased impurity removal step through a pressure swing adsorption device combined with a vacuum pump to remove an impurity in the raw material gas.
