Contribution of H₂ during the Two-Phase Anaerobic Digestion

Abstract:

In the process of anaerobic digestion for methane production, one-third of which is from hydrogen, another two-thirds from acetic acid. From the point of material and energy recovery, the energy conversion efficiency of alone hydrogen or methane production is less than co-generation of hydrogen and methane production. Because hydrogen production is also accompanied by acidification and syntrophic acetogenic fermentation process, it is technically feasible for alone hydrogen or methane production. As the two-phase anaerobic digestion separate the acidifying bacteria and methanogens in different reactors, blocking the synergy of the two different microbial community, we should provide scientific and technological support for two-phase anaerobic application.
