Abstract

A method of sequestering a greenhouse gas is described, which comprises: (i) providing a solution carrying a first reagent that is capable of reacting with a greenhouse gas; (ii) contacting the solution with a greenhouse gas under conditions that promote a reaction between the at least first reagent and the greenhouse gas to produce at least a first reactant; (iii) providing a porous matrix having interstitial spaces and comprising at least a second reactant; (iv) allowing a solution carrying the at least first reactant to infiltrate at least a substantial portion of the interstitial spaces of the porous matrix under conditions that promote a reaction between the at least first reactant and the at least second reactant to provide at least a first product; and (v) allowing the at least first product to form and fill at least a portion of the interior spaces of the porous matrix, thereby sequestering a greenhouse gas.

Claims

1. A method of sequestering a greenhouse gas comprising:

(i) forming a porous matrix having a predetermined shape and size;

(ii) providing the porous matrix having interstitial spaces and wherein a portion of the porous matrix comprises at least a first reactant

(iii) providing a solution carrying a first reagent that is capable of reacting with a greenhouse gas;

(iv) contacting the solution with a greenhouse gas under conditions that promote a reaction between the at least first reagent and the greenhouse gas to produce at least a second reactant in solution;

(v) allowing the at least second reactant in solution to infiltrate at least a substantial portion of the interstitial spaces of the porous matrix under conditions that promote a reaction between the at least second reactant and at least the portion of the porous matrix comprising the at least first reactant to provide at least a first product; and

(vi) allowing the at least first product to form and fill at least a portion of the interior spaces of the porous matrix, thereby sequestering a greenhouse gas.

2. The method of claim 1, wherein the greenhouse gas comprises at least one of carbon, sulphur, phosphorous, nitrogen, hydrogen, oxygen or a combination thereof.

3. The method of claim 1, wherein the solid matrix after the step (v) has a molar volume substantially the same as that before step (v).

4. The method of claim 1, wherein the solid matrix after the step (v) has a molar volume larger than that before step (v).

5. The method of claim 1, wherein the solid matrix after the step (v) has a molar volume smaller than that before step (v).

6. The method of claim 1, wherein the solid matrix after the step (v) has a density larger than that before step (v).

7. The method of claim 1, wherein the greenhouse gases is produced by a factory.

8. The method of claim 1, wherein the second reactant comprises at least one of a metal, metal oxide, metal hydroxide, metal sulfate, metal fluoride, metal titanate, or combinations thereof.

9. The method of claim 1, wherein the first reactant comprises oxalate, carbonate, sulfate, phosphate, citrate, metal ion, or combinations thereof.

10. The method of claim 1, wherein the first product is formed by precipitation.

11. The method of claim 1, wherein the first product comprises a carboxylate, a carbonate, an oxalate, or a combination thereof.

12. The method of claim 1, wherein the first product has a decomposition temperature at least about 1000°

C.

13. The method of claim 1, wherein the first product has an interconnecting network microstructure.

14. The method of claim 1, wherein the first reagent is in aqueous form.

15. The method of claim 1, wherein the method is performed at a temperature of less than about 300°

C.

16. The method of claim 1, wherein the method is performed at room temperature.

17. A method of making a ceramic, comprising:

(i) forming a porous matrix having a predetermined shape and size;

(ii) providing a porous matrix having interstitial spaces and wherein a portion of the porous matrix comprises at least a first reactant;

(iii) contacting the porous matrix with an infiltrating medium that carries at least a second reactant, which comprises a greenhouse gas;

(iv) allowing the infiltrating medium to infiltrate at least a portion of the interior spaces of the porous matrix under conditions that promote a reaction between the portion of the porous matrix comprising at least first reactant and the at least second reactant to provide at least a first product; and

(v) allowing the at least first product to form and fill at least a portion of the interstitial spaces of the porous matrix, thereby producing a ceramic,

wherein the method consumes and does not release significant amounts of greenhouse gas.

18. The method of claim 17, wherein the step (ii) to (iv) are repeated at least once.

19. A method of sequestering a greenhouse gas comprising:

(i) forming a porous matrix having a predetermined shape and size;

(ii) providing the porous matrix having interstitial spaces and wherein a portion of the porous matrix comprises at least a first reactant;

(iii) providing a solution carrying at least one greenhouse gas as a second reactant;

(iv) allowing the solution carrying the at least second reactant to infiltrate at least a substantial portion of the interstitial spaces of the porous matrix under conditions that promote a reaction between the at least second reactant and the portion of the porous matrix comprising the at least first reactant to provide at least a first product; and

(v) allowing the at least first product to form and fill at least a portion of the interior spaces of the porous matrix, thereby sequestering a greenhouse gas.

20. The method of claim 19, wherein the greenhouse gas is dissolved in the solution.
