Solid Porous Materials for Selective Capture and Separation of Sulfur Hexafluoride (SF₆).

ABSTRACT: Developing technologies to capture, purify, and reuse potent greenhouse gases such as sulfur hexafluoride (SF₆) is crucial because of their high global warming potential. Porous solid matrices are promising candidates for this purpose, due to their high surface areas and pore volumes. Herein, two coconut shell-derived activated carbons (AC) (CS-CO₂ and CS-ZnCl₂), obtained through physical and chemical activation, are evaluated and compared with two commercial adsorbents: an AC monolith (ACM) and a metal-organic framework. The adsorption capacities for SF₆ and nitrogen (N₂) are measured gravimetrically at three temperatures: 283.15, 303.15, and 323.15 K. The experimental data are fitted using the Toth model, and the impact of temperatur
