Abstract
Hydrogenothrophic biomethanation of CO2 is an attractive alternative method for either to increase biogas production or upgrading biogas in biogas plants as a carbon capture and utilization (CCU) technology. The use of various packaging materials providing efficient cell immobilization can increase hydrogenotrophic biomethanation efficiency. For this purpose, the effect of two packing materials (ceramic ball and glass pipe) on hydrogenotrophic biomethanation efficiency were investigated. It was found that glass pipe outcompeted ceramic ball in terms of both H2 utilisation efficiency (55% for ceramic ball and 85% for the glass pipe), high CH4 content in the headspace (65% for ceramic ball and 78% for the glass pipe) and methane formation rates (MFR: 3.9 and 4.8 m3CH4/m3reactor/day for ceramic ball and glass pipe, respectively).
