Abstract

Embodiments of the present invention feature article of manufacture, methods of making and methods of using a paste of the reaction product of an organic amine and support particles, shaped as pellets, sheets, films, rings discs or other forms useful for scrubbing carbon dioxide from emissions and the atmosphere.

Claims

1. A malleable material consisting essentially of a liquid amine, a plurality of support particles, and water.

2. The malleable material of claim 1, wherein the amine is polyethylenimine (PEI), aziridine, ethanolamine, diethanolamine, an ethylenamine, or mixtures thereof.

3. The malleable material of claim 1, wherein the support particles are composed of carbon, silica, alumina, or mixtures thereof.

14. The malleable material of claim 1, wherein the material is flowable.

15. The malleable material of claim 1, wherein the material has a large solids content held in suspension.

16. The malleable material of claim 1, wherein the material has a viscosity in the range of about 10,000 cP to about 10,000,000 cP.

4. A solid sorbent for scrubbing air consisting essentially of a plurality support particles and at least one organic amine, wherein the organic amine binds the plurality of support particles to one another and into shaped forms larger than a single support particle.

5. The sorbent of claim 4, wherein the amine is polyethylenimine (PEI), aziridine, ethanolamine, diethanolamine, an ethylenamine, or mixtures thereof.

6. The sorbent of claim 4, wherein the support particles are composed of carbon, silica, alumina, or mixtures thereof.

7. The sorbent of claim 4, wherein the shaped form has at least one dimension greater than about 0.1 mm.

8. The sorbent of claim 4, wherein the shaped form has at least one dimension greater than about 10 mm.

9. The sorbent of claim 4, wherein the shaped form is a pellet, filament, sheet, globules, cylinder, sphere, spheroid, ellipsoid, cube, rectangle, triangle, ring, or disc.

10. A method of making the solid sorbent for scrubbing air of claim 4, comprising:

adding at least one liquid amine to a solvent and a plurality of support particles to form a malleable material;

forming the malleable material into shapes or granules of substantially similar form and dimensions; and

drying the formed shapes to remove substantially all of the solvent.

11. The method of claim 10, wherein the dried formed shapes are about 20% to 60% by weight organic amine and about 40% to 80% by weight support particle.

12. The method of claim 10, wherein the malleable material is formed into shapes by extrusion, molding, cutting or pelletization.

13. The method of claim 10, wherein the malleable material is formed into pellets, filaments, sheets, globules, cylinders, spheres, spheroids, ellipsoids, cubes, blocks, rectangles, pyramids, ring, or discs.

17. The method of claim 10, wherein the solvent is water.
