Enhanced bioconversion of hydrogen and carbon dioxide to methane using a micro-nano sparger system: mass balance and energy consumptionElectronic supplementary information (ESI) available. See DOI: 10.1039/c8ra02924e
Simultaneous CO 2 removal with renewable biofuel production can be achieved by methanogens through conversion of CO 2 and H 2 into CH 4 . However, the low gas-liquid mass transfer ( k L a ) of H 2 limits the commercial application of this bioconversion. This study tested and compared the gas-liquid...

limits the commercial application of this bioconversion. This study tested and compared the gas-liquid mass transfer of H
2
by using two stirred tank reactors (STRs) equipped with a micro-nano sparger (MNS) and common micro sparger (CMS), respectively. MNS was found to display superiority to CMS in methane production with the maximum methane evolution rate (MER) of 171.40 mmol/L
R
/d and 136.10 mmol/L
R
/d, along with a specific biomass growth rate of 0.15 d
−1
and 0.09 d

, respectively. Energy analysis indicated that the energy-productivity ratio for MNS was higher than that for CMS. This work suggests that MNS can be used as an applicable resolution to the limited
