Progress of Research on Two-Phase Anaerobic Fermentation of Hydrogen Production and Methanogenesis

Abstract

The technology of two-phase anaerobic fermentation of hydrogen production and methanogenesis has attracted wide attention at home and abroad. It is the key of research on two-phase anaerobic fermentation to raise hydrogen productivity of hydrogen fermentor and the conversion rate of biological energy source of two- phase system. This paper summarizes the latest findings in research and application of two-phase anaerobic technology in the latest years, emphatically introduces the use and operation of substrate, superiority of phase separation and superior bacteria between the two phases in two-phase anaerobic fermentation and puts forward suggestions on the prospect of two-phase anaerobic fermentation.
