Anaerobic digestion is a technology that uses organic waste to produce biogas as renewable energy. However, a low methane content (50~70%) and the presence of CO2 (30~50%) are reasons that prevent biogas applications (e.g., natural gas grid injection). In this thesis, high-pressure anaerobic digestion was used to obtain high content biogas (>85%). The process of high-pressure anaerobic digestion was investigated using pressure, substrate types, and hydraulic retention time. In addition, H2 injection can further increase the methane content (94%), which overcomes the carbon acid accumulation problem in a pilot-scale reactor. This result suggests that the combination of high-pressure and H2 addition technologies could be applied in biogas ...
