Potassium Silicate as Low-Temperature Binder in 3D-Printed Porous Structures for CO₂ Separation.

ABSTRACT: Activated carbon sorbents were directly 3D-printed into highly adaptable monolithic/multi-channel systems by using potassium silicate as a low-temperature binder. By employing emerging 3D-printing technologies, monolithic structured sorbents were printed and fully characterized using N₂, Ar, and CO₂-sorption and Hg-intrusion porosimetry. The CO₂-capture performance and the required temperature for active-site regeneration were evaluated by thermogravimetric analysis-looping experiments. A mechanically stable activated carbon sorbent was developed with an increased carbon capture performance, even when a room-temperature regeneration by N₂ purging was applied. Although the CO₂ uptake slightly dropped after several cycles due to incomple
