High-Performance Biogas Upgrading Using a Biotrickling Filter and Hydrogenotrophic Methanogens
TL;DR: The development of a biotrickling filter (BTF) to upgrade biogas, which is achieved by adding H2 to reduce CO2, and DNA sequencing showed that only 27% of the biomass was composed of Euryarchaeota, the phylum which includes methanogens, suggest that optimizing the methanogen density and activity could possibly reach even higherBiogas upgrading rates.
Journal ArticleDOI
Detailed investigations of dissolved hydrogen and hydrogen mass transfer in a biotrickling filter for upgrading biogas
TL;DR: Results demonstrated that the main resistance resides in the trickling liquid film and that promoting direct gas-biofilm mass transfer could improve upgrading performance by about 20%, and that increasing the gas velocity lowered the upgrading capacity.
Journal ArticleDOI
Biological Co-treatment of H2S and reduction of CO2 to methane in an anoxic biological trickling filter upgrading biogas.
TL;DR: Overall, this study showed that simultaneous biogas upgrading and H2S removal in a single bioreactor is possible, but that achieving high yields for both reactions requires further research in process and culture optimization.
Journal ArticleDOI
Development and Validation of a Comprehensive Model for Biotrickling Filters Upgrading Biogas
TL;DR: In this paper, the authors developed, validated, and analyzed a conceptually correct mathematical model for biogas upgrading biological trickling filter (BTF) reactors, which considers convective transport and dispersion of gases through the fixed bed and mass transfer and reaction of absorbed gases in immobilized biofilms.
