Design of Electrified Fiber Sorbents for Direct Air Capture with Electrically-Driven Temperature Vacuum Swing Adsorption.

ABSTRACT: Joule heating is becoming accepted as a highly efficient regeneration technique for temperature vacuum swing adsorption in direct air capture (DAC). This acknowledgment arises from its ability to rapidly generate and transfer heat, along with the convenience of obtaining electrical power from renewable sources. This study presents a unique electrified fiber sorbent (i.e., e-fiber) design that facilitates Joule heating, enabling energy-efficient electrically-driven temperature-vacuum swing adsorption (e-TVSA) for DAC. The e-fiber sorbent is produced via a dip coating technique, in which a silver composite solution is applied to the surface of an open-porous polymer matrix. The resulting ultra-thin, interconnected porous conductive layer on the fiber surface not only minimizes the increase i
