A Single-Culture Bioprocess of Methanothermobacter thermautotrophicus to Upgrade Digester Biogas by CO2-to-CH4 Conversion with H2
Bioreactor performance for Experiment 3. Volumetric methane production rates (a) and hydrogen conversion efficiencies (b) for bioreactor runs in which the methane influent rate was varied between 0 and 0.4 L/min. Data were gathered for three different hydrogen influent rates. The error bars represent the observed variance between runs for each bioreactor condition.
