Fabrication of silica aerogel and carbon–silica composite for dynamic adsorption of benzene from dry and wet gas streams

In the present study, white kaolin-derived silica (SA) and silica-carbon aerogel composite (CSA) were successfully synthesised as useful adsorbents for effective removal of benzene from dry wet gas streams. The physicochemical features characterised using SEM, BET, XPS, TGA, adsorption properties investigated through breakthrough time curves equilibrium study. specific surface areas SA CSA 628 783 m2 g−1, respectively, demonstrating high porosity adsorbents. dynamic isotherm performances confirmed that both have superior Khan developed fittest model among two- three-parameter models studied provided a maximum capacity 366.2 224.4 mg respectively. Furthermore, reusability tests revealed could be efficiently recovered at 180°C. Our experimental outcomes indicated prepared can applied efficient inexpensive gaseous
