This paper used annua as material to do a biogas fermentation experiment. The result suggests that biogas-fermentation by pretreated annua is a preferable approach compared with methane production followed by hydrogen production, only methane production, or only hydrogen production, due to its decreasing overall fermentation time, and increasing material utilization efficiency and energy conversion efficiency. It shows that the TS and VS utilization ratio of first hydrogen production then methane production is higher than that of first methane production then hydrogen production.
