Title:

METHOD OF RECOVERING HYDROGEN FROM ORGANIC WASTE

Document Type and Number:

WIPO Patent Application WO/2004/020331

Kind Code:

A1

Abstract:

A method of recovering hydrogen, comprising heating organic waste at 500 to 600°C in nonoxidative atmosphere, mixing gas resulting from thermal decomposition with steam at 900 to 1000°C and purifying the thus obtained reformed gas to thereby recover hydrogen. This method enables effective utilization of energy and gas obtained from organic waste materials, for example, thined wood, driftwood, waste wood, waste plastic, garbage, polluted sludge, mown grass, paper-making sludge, etc.
