High-Pressure Adsorption of CO2 and CH4 on Biochar-A Cost-Effective Sorbent for In Situ Applications

Original language description

The search for an effective, cost-efficient, and selective sorbent for CO2 capture technologies has been a focus of research in recent years. Many technologies allow efficient separation of CO2 from industrial gases; however, most of them (particularly amine absorption) are very energy-intensive processes not only from the point of view of operation but also solvent production. The aim of this study was to determine CO2 and CH4 sorption capacity of pyrolyzed spruce wood under a wide range of pressures for application as an effective adsorbent for gas separation technology such as Pressure Swing Adsorption (PSA) or Temperature Swing Adsorption (TSA). The idea behind this study was to reduce the carbon footprint related to the transport and manufacturing of sorbent for the separation unit by replacing it with a material that is the direct product of pyrolysis. The results show that pyrolyzed spruce wood has a considerable sorption capacity and selectivity towards CO2 and CH4. Excess sorption capacity reached 1,4 mmol.gMINUS SIGN 1 for methane and 2.4 mmol.gMINUS SIGN 1 for carbon dioxide. The calculated absolute sorption capacity was 1.75 mmol.gMINUS SIGN 1 at 12.6 MPa for methane and 2.7 mmol.gMINUS SIGN 1 at 4.7 Mpa for carbon dioxide. The isotherms follow I type isotherm which is typical for microporous adsorbents.
