In this contribution, the effect of the presence of a presumed inert gas like in the feed gas on the biological methanation of hydrogen and carbon dioxide with Methanothermobacter marburgensis was investigated. can be found as a component besides in possible feed gases like mine gas, weak gas, or steel mill gas. To determine whether there is an effect on the biological methanation of and from renewable sources or not, the process was investigated using feed gases containing , , and in different ratios, depending on the content. A possible effect can be a lowered conversion rate of and to . Feed gases containing up to 47% were investigated. The conversion of hydrogen and carbon dioxide was possible with a conversion rate of up to 91% but was limited by the amount of when feeding a stoichiometric ratio of 4:1 and not by adding to the feed gas.
