Abstract: The present document describes a process for production of hydrogen gas (H2) from fermentation of crude glycerol with a hydrogen producing microorganism in a bioreactor. The process comprises the step of introducing a volume of crude glycerol in a fermentation mixture which comprises a fermentation medium comprised of crude glycerol and hydrogen producing microorganisms under a fermentative hydrogen production condition, and then removing a volume of the fermentation mixture equal to the second volume of the crude glycerol, to maintain constant the total volume of the fermentation mixture.

Abstract: The present document describes a system and a process for the thermochemical treatment a matter containing organic compounds such as biomass, for the production of useful energetic products such as biochar, bio-oil and gases from non-condensed vapors. The system comprises a reactor comprising a feedstock reservoir having entry and exit, a thermochemical reaction chamber having an entrance disposed under and coupled to the reservoir exit, an exit, and a first heating means for thermal treatment of the matter to produce a solid and a vapor. The system also comprises a feeder having at least one substantially vertical auger operatively coupled to the feedstock reservoir and the thermochemical reaction chamber exit to drive the matter downwardly from the feedstock reservoir exit through the thermochemical reaction chamber.
