HYDROGEN GENERATOR USING BY-PRODUCT GAS FROM IRON MANUFACTURING AND PREPARATION METHOD OF HYDROGEN USING SAME

摘要

Provided is a preparation method of hydrogen using by-product gas from iron manufacturing. The preparation method of hydrogen using by-product gas from iron manufacturing of the present invention includes: a gas purification step of purifying the by-product gas; a hydrogen separation step of separating hydrogen from the by-product gas through hydrogen pressure swing adsorption (PSA); a reformation step of making remaining methane-rich gas after hydrogen separation react with a catalyst to be reformed; an aqueous purification step of purifying the reformed methane-rich gas through aqueous purification; and a hydrogen separation step of separating hydrogen from the gas passed through the aqueous purification step through hydrogen pressure swing adsorption (PSA).;COPYRIGHT KIPO 2018
