Hydrogenotrophs-Based Biological Biogas Upgrading Technologies [PDF]

Frontiers in Bioengineering and Biotechnology, 2022
Biogas produced from anaerobic digestion consists of 55–65% methane and 35–45% carbon dioxide, with an additional 1–2% of other impurities. To utilize biogas as renewable energy, a process called biogas upgrading is required.
