Abstract
A porous sorbent ceramic product includes a three-dimensional structure having an electrically conductive ceramic material, wherein the conductive ceramic material has an open cell structure with a plurality of intra-material pores, a sorbent additive primarily present in the intra-material pores of the conductive ceramic material for adsorption of a gas, and at least two electrodes in electrical communication with the conductive ceramic material.
Claims20
A porous sorbent ceramic product comprising:
- a three-dimensional structure comprising an electrically conductive ceramic material, wherein the conductive ceramic material has an open cell structure with a plurality of intra-material pores;
- a sorbent additive primarily present in the intra-material pores of the conductive ceramic material for adsorption of a gas;
- and
- at least two electrodes in electrical communication with the conductive ceramic material.
A method of forming a product for separating gases, the method comprising:
- forming a three-dimensional ceramic support, wherein the three-dimensional ceramic support comprises an electrically conductive ceramic material configured for joule heating,
- heating the three-dimensional ceramic support at a temperature for an effective duration of time to result in the conductive ceramic material having a plurality of intra-material pores;
- and
- incorporating a sorbent additive into the intra-material pores of the conductive ceramic material.
A method of using a porous sorbent ceramic product having a sorbent additive for separating gases, the method comprising:
- contacting a gas stream comprising a mixture of more than one gas with the porous sorbent ceramic product for causing sorption of a first of the gases by the sorbent additive;
- and
- applying an electrical current to the porous sorbent ceramic product for causing joule heating of the porous sorbent ceramic product to a pre-defined temperature for desorbing the first gas from the sorbent additive.
