Title:
METHOD AND APPARATUS FOR PRODUCING HYDROGEN AND METHANE USING MICROORGANISM
Document Type and Number:
Japanese Patent JP2003135089
Kind Code:
A
Abstract:

To fix the condition to sufficiently exhibit the action of a hydrogen- producing microorganism.

A regenerable organic resource is used as a raw material, heat- treated at 50-90°C and subjected to hydrogen fermentation with a hydrogen- producing microorganism to produce a biogas composed mainly of hydrogen and carbon dioxide. The hydrogen fermentation residue left after the generation of biogas is subjected to methane fermentation and the produced methane gas is used as a fuel, etc. Since the heat-treatment is carried out under an easily practicable condition, the method is effective for the practical use of the technology to produce hydrogen from a regenerable organic resource.
