二酸化炭素吸着のためのエタノール処理による改質したロウソク由来すす粒子の表面積の増大
Carbon dioxide (CO2) adsorption, a known greenhouse gas, requires processes and technologies to remove CO2 from the atmosphere. Recently, carbon-based adsorbents have been used for CO2 adsorption, and to enhance CO2 adsorption, surface treatment with ethanol was necessary. However, the CO2 adsorption mechanism before and after ethanol surface treatment of soot was an area lacking in research. Therefore, this study investigated the effects of ethanol treatment on the soot surface and adsorption performance of candles. Based on adsorption isotherms, the results suggested that the particles after ethanol treatment had a non-uniform surface with a greater number of CO2 adsorption sites compared to untreated soot. 温室効果ガスとして知られる二酸化炭素（CO2）の吸着には、大気中のCO2を除去するプロセスや技術が必要である。近年、CO2吸着には炭素系吸着剤が使用されており、CO2吸着を促進するためにはエタノールによる表面処理が必要であった。しかし、煤煙のエタノール表面処理前後のCO2吸着メカニズムについては、研究が不足している。そこで本研究では、エタノール処理がすす粒子表面およびロウソク由来すすの吸着性能に及ぼす影響について検討した。吸着等温線から、エタノーあル処理後の粒子は、未処理のすす粒子に比べてCO2吸着サイトの数が多く、不均一な表面であることが示唆された。
