Performance enhancement of biological methanation with trickle bed reactors by liquid flow modulation

Experiments were carried out to investigate the influence of liquid flow modulation of trickle bed reactors ( TBR ) on biological hydrogen methanation ( BHM ). The modulation promises to improve the gas‐liquid mass transfer and has already been demonstrated in trickle bed reactors of other fields of application. Therefore, the influence of four different circulation intervals with pauses from two to 1,440 min was investigated in TBR for BHM ....
