Title:
METHOD AND EQUIPMENT FOR PRODUCING HYDROGEN-ENRICHED GAS
Document Type and Number:
WIPO Patent Application WO/2022/230568
Kind Code:
A1
Abstract:
Provided is a method for producing a hydrogen-enriched gas, the method comprising: (A) a step for generating a hydrogen-and-oxygen-containing mixed gas in a reactor that splits water into hydrogen and oxygen by means of sunlight in the presence of a photocatalyst; (B) a step for collecting the mixed gas in a storage tank; (C) a step for supplying the mixed gas in the storage tank to a gas separator that includes a membrane having the ability to split into hydrogen and oxygen; and (D) a step for separating a hydrogen-enriched gas from the mixed gas in the gas separator.
