DUAL METHOD OF HYDROGEN PRODUCTION

摘要

The present invention provides a dual method of hydrogen production, wherein organic feed material is heated with excess or diverted heat from a secondary hydrogen production method, thereby substantially deactivating or killing methanogens within the organic feed material. Hydrogen producing microorganisms contained or added to the organic feed material metabolize the organic feed material in a bioreactor to produce hydrogen in a primary hydrogen production method. As the methanogens are no longer substiantially present to convert produced hydrogen to methane, a biogas that contains hydrogen without substantial methane can be produced.
