A Single-Culture Bioprocess of Methanothermobacter thermautotrophicus to Upgrade Digester Biogas by CO2-to-CH4 Conversion with H2
Table 1
The percentage of methane content in influent gas and total influent flow rate () for Experiment 3. Three different methane influent rates () were evaluated for three different hydrogen influent rates () while maintaining the stoichiometric 4 : 1 H2 : CO2 gas mixture ratio. The total influent flow rate () is shown in brackets in L/min.
