| Popis: | The anaerobic digestion of cellulose was assessed in batch and semi-continuous studies using a carbon felt fixed-bed reactor. In the batch operation, the volatile solids reduction (%) and the cumulative methane production during the mesophilic and thermophilic digestion were 52.2% and 15.9%, 96.7 and 49.2 ml/g-total solid fed, respectively. After 99 days of semi-continuous mesophilic digestion, the degradation of cellulose reached its highest level of 67.6% at the hydraulic retention time of 9 days. The methane production and methane concentration of biogas from the bioreactor were maintained at a steady state. The fixed-bed reactor with carbon felt would be suitable for the efficient anaerobic digestion of cellulose. The biomass distribution in the reactor was, in the liquid phase 0.73 g/l-reactor, in the felt 1.59 g/l-reactor, and on the felt surface 9.86 g/l-reactor, which indicated that most of the microbes were immobilized on the carbon felt fixed-bed in the reactor. |
