SYSTEM FOR SUSTAINED MICROBIAL PRODUCTION OF HYDROGEN GAS IN A BIOREACTOR

摘要

The present invention provides a system of hydrogen production 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 controlled by providing a pH controller for controlling the pH of an organic feed material that is metabolized by the hydrogen producing microogranisms held within the bioreactor, wherein the pH of the bioreactor is preferably between about 3.5 and 6.0 pH, and by heating the organic feed material prior to entry into the bioreactor. Futher, the ORP of reaction occurring within the bioreactor are maintained at about -300 to -450 mV.
