Abstract:
An advantage of biogas is the possible distribution via the public natural gas grid to enable efficient energy utilization. However, injection into the grid requires an energy intensive upgrade. A carbon dioxide reduction before the biogas upgrade process could enhance the energy efficiency. To research the effect of anaerobic hydrolysis on the methane content of the biogas, one-phase and two-phase digestion trials were carried out. Monitoring of the trials was done with a carbon mass balance to prove the data. The results showed that higher methane contents in the biogas could be achieved, but at the same time biogas yield decreased due to gas production in the hydrolysis.
