Impact of operational conditions on methane yield and microbial community composition during biological methanation in in situ and hybrid reactor systems. [PDF]

Biotechnol Biofuels, 2021
Background Biogas can be upgraded to methane biologically by adding H2 to biogas reactors. The process is called biological methanation (BM) and can be done in situ in a regular biogas reactor or the biogas can be transferred to a separate ex situ ...
