PROCESS FOR PRODUCING HYDROGEN FROM GAS GENERATED FROM DEVICE FOR TREATING WASTE

摘要

PROBLEM TO BE SOLVED: To provide a process for producing hydrogen by subjecting domestic wastes, and the like, to a thermal melting and gasifying treatment, washing the generated gas with water, compressing and cooling the washed gas and then delivering the produced gas into a hydrogen-separating device to produce the hydrogen from the raw material gas containing the hydrogen, carbon monoxide and carbon dioxide. SOLUTION: This process for producing hydrogen comprises feeding non- classified domestic wastes or industrial wastes containing liquid and/or solid pollutants into a tunnel 3 heated at >=100 deg.C to subject the waste to a melting and gasifying treatment at a high temperature of >=1,000 deg.C in the presence of oxygen, quenching the collected synthetic gas 7, washing the gas with water to remove impurities, compressing and cooling the gas 15 as raw material of the hydrogen, and then directly delivering the generated gas 22 into a hydrogen- separating device 30 to produce the hydrogen.
