Abstract

A composite material for gas capture including CO 2 capture and capture of other gases. The composite material includes solid or liquid reactive material, filler material, and a gas-permeable polymer coating such that the reactive material forms micron-scale domains in the filler material.

First claim

The invention claimed is:

1. A method of making a reactor for removing a single gas or multiple gases from a gas stream containing the single gas or the multiple gases, comprising the steps of:
providing a filler material,
providing a sorbent material,
extruding said filler material and said sorbent material to produce an extrudant, and
providing a gas-permeable polymer coating layer around said extrudant to produce the reactor.

2. The method of making a reactor for removing a single gas or multiple gases from a gas stream containing the single gas or the multiple gases of claim 1 wherein said sorbent material includes units of sorbent material and wherein said units of sorbent material are units of carbon dioxide stripping material.

3. The method of making a reactor for removing a single gas or multiple gases from a gas stream containing the single gas or the multiple gases of claim 1 wherein said sorbent material includes units of sorbent material and wherein said units of sorbent material are units of stripping material for stripping other gasses than carbon dioxide.

4. The method of making a reactor for removing a single gas or multiple gases from a gas stream containing the single gas or the multiple gases of claim 1 wherein said sorbent material includes units of sorbent material and wherein said units of sorbent material are liquid units of carbon dioxide stripping material.

5. The method of making a reactor for removing a single gas or multiple gases from a gas stream containing the single gas or the multiple gases of claim 1 wherein said sorbent material includes units of sorbent material and wherein said units of sorbent material are liquid droplets of carbon dioxide stripping material encapsulated in capsules.

6. The method of making a reactor for removing a single gas or multiple gases from a gas stream containing the single gas or the multiple gases of claim 1 wherein said sorbent material includes units of sorbent material and wherein said units of sorbent material are solid units of carbon dioxide stripping material.

7. The method of making a reactor for removing a single gas or multiple gases from a gas stream containing the single gas or the multiple gases of claim 1 wherein said sorbent material includes units of sorbent material and wherein said units of sorbent material are solid droplets of carbon dioxide stripping material encapsulated in capsules.

8. The method of making a reactor for removing a single gas or multiple gases from a gas stream containing the single gas or the multiple gases of claim 1 wherein said sorbent material includes units of sorbent material and further comprising the step of forming said extrudant into a flat sheet of said extrudant with said filler in said extrudant, with said units of sorbent material in said extrudant with said filler; and with said gas-permeable polymer coating layer around said extrudant.

9. The method of making a reactor for removing a single gas or multiple gases from a gas stream containing the single gas or the multiple gases of claim 1 wherein said sorbent material includes units of sorbent material and further comprising the step of forming said extrudant into a rolled sheet of said extrudant with said filler in said extrudant, with said units of sorbent material in said extrudant with said filler; and with said gas-permeable polymer coating layer around said extrudant.

10. The method of making a reactor for removing a single gas or multiple gases from a gas stream containing the single gas or the multiple gases of claim 1 further comprising the step of forming said extrudant into an entangled mass of filaments.

11. The method of making a reactor for removing a single gas or multiple gases from a gas stream containing the single gas or the multiple gases of claim 1 further comprising the step of forming said extrudant into a layered mass of filaments.

12. The method of making a reactor for removing a single gas or multiple gases from a gas stream containing the single gas or the multiple gases of claim 1 further comprising the step of forming said extrudant into a woven mass of filaments.
