未利用植物系バイオマスのメタン発酵 Methane fermentation of unused plant biomass
Methane fermentation of various plant biomass, including paper, wood, rice straw, rice hulls, common reed, wild rice and two kinds of weed, was investigated in a batch vial test. Gompertz model fit the experimental data well, and was used to estimate the maximum methane potential and so on. Paper showed the highest methane conversion efficiency of 87% (based on CODcr), while rice hulls and wild rice the lowest of 25%. It is concluded that the biomass studied can be used as part of feed for existing methane fermentation facilities.
