Abstract

The upgrading of biogas to natural gas quality (above 90% CH₄) will broaden its application. A novel ex-situ immobilized biomethanation bioreactor (IBBR) was developed for biologically upgrading biogas by reducing CO₂ to CH₄ using H₂ as an electron donor. The developed process is based on immobilized microorganisms within a polymeric matrix enabling the application of high recirculation to increase the H₂ bioavailability. This generated an increase in the consumption rate of H₂ and the production rate of CH₄. This process was demonstrated at laboratory-scale system, where the developed process led to a production of 80%–89% CH₄ with consumption of more than 93% of the fed H₂. However, a lower CH₄ content was achieved in the bench-scale system, likely as a result of lower H₂ consumption (63%–90%).
