本研究では、コロンビアの中マグダレナ渓谷を対象に、サトウキビバガス由来のアミン官能化活性炭（AAC）を用いたCO2回収・利用システムを実験室規模で評価した。AACは高い比表面積を持ち、Co-Mn触媒と組み合わせることで液体炭化水素への選択性が向上した。この結果は、バイオベース炭素材料がCCUSシステムの性能向上に寄与する可能性を示すが、実用化には反応速度や触媒安定性の検討が必要である。
English
This study evaluates a lab-scale CO2 capture and utilization system using amine-functionalized activated carbon (AAC) from sugarcane bagasse, targeting the Middle Magdalena Valley in Colombia. The AAC, with high surface area, combined with a Co-Mn bimetallic catalyst, improved selectivity for liquid hydrocarbons via Fischer-Tropsch synthesis. Results suggest bio-based carbons can enhance CCUS performance, but further studies on kinetics, gas composition, and catalyst stability are needed for scalability.

📄 Abstract（原文）
The rise in atmospheric CO2 concentrations poses a significant challenge for industrial decarbonization, particularly in regions that rely heavily on hydrocarbons, such as the Middle Magdalena Valley (MMV) in Colombia. This study evaluates, at the laboratory scale, an integrated approach to CO2 capture and utilization using amine-functionalized activated carbon (AAC) derived from sugarcane bagasse, which serves as both an adsorbent and a catalytic support. The AAC, synthesized via pyrolysis and chemical functionalization, exhibited a high specific surface area of 1,456 m2/g, thereby facilitating CO2 adsorption and improving catalyst dispersion. The hydrogenation of CO2 via Fischer-Tropsch synthesis was carried out in a batch reactor for 24 h at temperatures ranging from 220 to 260 °C, using H2 and CO2 as reactants. A comparative experimental approach was implemented to evaluate system configurations with and without AAC and a Co–Mn bimetallic catalyst. The use of the AAC/Co6/MnOx mixture up to 260 °C demonstrated superior selectivity for liquid hydrocarbons compared to other treatments, increasing by 24.37% relative to the initial squalane mass. These results indicate that functionalized bio-based carbons can improve catalyst performance under batch conditions. However, further studies are needed to examine reaction kinetics, the effects of gas composition, and catalyst stability in order to assess the scalability and applicability of this approach in CCUS systems.
