A recently granted patent (Publication Number: US11883793B2) discloses a porous sorbent ceramic product designed for gas adsorption. The product features a three-dimensional structure made of an electrically conductive ceramic material with open cell structures containing intra-material pores. These pores house a sorbent additive responsible for gas adsorption, with at least two electrodes in electrical communication with the conductive ceramic material. The structure is capable of joule heating upon the application of an electrical current, facilitating the release of adsorbed gas from the sorbent additive. Additionally, the product includes inter-material pores with specific diameter ranges and physical properties of the conductive ceramic material, enhancing its efficiency in gas adsorption.

Furthermore, the patent describes a method for forming the porous sorbent ceramic product, involving the creation of a three-dimensional ceramic support with electrically conductive ceramic material suitable for joule heating. The support is heated to develop intra-material pores and then infused with a sorbent additive. The method also includes specific steps like immersing the ceramic support in a sorbent additive-solvent mixture and subsequent drying to remove the solvent. The resulting product exhibits a porosity range and geometric features that optimize gas adsorption efficiency. The patent's innovative approach to utilizing electrically conductive ceramic materials for gas adsorption applications opens up possibilities for more effective and sustainable sorbent products in various industries.
