System for sustained microbial production of hydrogen gas in a bioreactor utilizing a circulation system

摘要

The present invention provides an apparatus for the production of hydrogen from microorganisms, wherein a bioreactor provides an environment conducive to the production of hydrogen from hydrogen producing microorganisms and restrictive to the production of methane from methanogens. The environment is adjusted to a pH conducive to the growth and metabolism of hydrogen producing microorganisms within the bioreactor, wherein the pH of the organic feed material is preferably between about 3.5 and 6.0 pH. The method further includes a circulation system to create directional Low within the bioreactor.
