METHOD AND APPARATUS FOR PRODUCTION OF HYDROGEN BY GASIFICATION OF COMBUSIBLE MATERIAL

Document Type and Number:

WIPO Patent Application WO/2000/059825

Kind Code:

A1

Abstract:

A method for the production of hydrogen having a gasification process (1) which gasifies a combusible material (a) and a gas treating process (1a) which purifies a gas (b) formed in the gasification process (1) to produce hydrogen, characterized in that the gas treating process (1a) comprises a gas cleaning step (2) contacting the formed gas (b) obtained in the gasification process (1) with water or an alkaline solution to remove a dust and a trace amount of an acidic gas such as hydrogen chloride, hydrogen sulfide or the like from the gas by absorption, and a carbon monoxide adsorbing step (7) contacting the formed gas (b) having been cleaned in the gas cleaning step (2) with an adsorption agent for carbon monoxide to separate carbon monoxide from the gas. The method can be employed for recovering the chemical energy stored in a combustible material in the form of hydrogen gas and further converting it to electric energy with high efficiency.
