| Abstract: | This paper reported Vetiveria zizanioides can produce methane by anaerobic batch fermentation at 28℃. With 90 days of HRT and 10.47% of TS in 1200ml reactor, its biogas yield has been 471ml/g TS and 512ml/g VS. The calorific value of V. zizanioides is 17.784 kJ/g, the energy conversion efficiency can get to 52.18% by the anaerobic digestion. The content of cellulose, fat and lignin did not change significantly after biogas fermentation. |
