Adsorption and Biomass: Current Interconnections and Future Challenges
Résumé
Purpose of Review :
The present study focuses on investigating the interconnections between adsorption technology and biomass energy production processes. A critical review on the different roles and perspectives of adsorption in these processes and on the potential of biochar as a solid bio-sorbent is investigated.
Recent Findings :
Adsorption plays a role in CO2 capture as a purification final step and can be viable for capture at low to medium scale. Promising materials and processes are proposed in the literature. Biochar produced from biomass pyrolysis shows properties comparable with commercialized adsorbents.
Summary :
Adsorption in biomass associated with carbon capture and storage (Bio-CCS) is expected to grow if new adsorbents and processes are performant at larger scale. New biomass-based processes involving adsorption can be developed; methanation coupled with methanization is one of them. Biochar is technologically ready for water depollution and soil amendment but further work is needed for CO2 capture applications. These challenges will necessitate adapted policies and R&D to decrease the production costs. Industrial exploitation of biomass necessitates interdisciplinary work.
