Abstract

The three kinds of energy grasses: Pennisetum purpureu, Miscanthus sinensis and Miscanthus floridulus from the Southchina area were conducted for biogas by using batch anaerobic digestion technical process at mesophilic temperature (35 ± 1oC), in this paper. The experiment results showed that the three kinds of energy grasses had different anaerobic fermentation performances: the highest daily biogas production were 31.33, 24.84 and 19.51 Nml•(gVSadded)−1•d−1, the cumulative biogas production were 355.78, 285.58 and 235.38 Nml•(gVSadded)−1, and the cumulative CH4 production were 166.43, 109.89 and 97.20 Nml•(gVSadded)−1, accounted for 33.83%, 21.67% and 19.48% of the theoretical CH4 production, respectively. Biogas yield of Pennisetum purpureu was obviously higher than that of the others, which was mainly because it had higher content of easily biodegradable organics. Modified Gompertz equation could be used well to fit the anaerobic digestion process of energy grass producing biogas. The simulation results were that the cumulative biogas production of the three kinds of grasses were 344.81, 290.11 and 279.01 Nml•(gVSadded)−1, and the delay times of anaerobic digestion tests were 5.96, 0.71 and 0 d.
