Discussing on Biochemical Pathway of Anaerobic Fermentation for Hydrogen and Methane Producition by Eupatorium Adenophorum Spreng based on Biochemical Material

摘要

The biochemical pathway of fermentation for methane and hydrogen production by Eupatorium adenophorum Spreng E. adenophorum is different from only methane production, only hydrogen production, or methane production followed by hydrogen production. This paper is focused on biochemical metabolic mechanism of relationship between methane and hydrogen production, in order that it provide theoretical basis for utilization of biomass anaerobic fermentation in the future. E. adenophorum could be made use of an energy plant for biogas production, despite the fact that EaS straw rich in cellulose. We speculate that utilizing E. adenophorum as a biogas feedstock will maximize energy conversion efficiency and this method can maximize benefits with respect to carbon management and greenhouse gas emissions, creating benefits for both environmental remediation and energy production [1]. Compared with only methane production or only hydrogen production, the hydrogen fermentation process previous methane fermentation, by regulating pH value of E. adenophorum fermentation system, can increase material utilization ratio and shorten the methane fermentation reaction time. It has better material utilization ratio and energy conversion efficiency than that of methane production previous hydrogen production [2].
