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 monolithic compact produced by a carbon capturing, carbon sequestering process, or a combination thereof, which process comprises allowing at least one component of a porous matrix having a shape to undergo a reaction with at least a first reactant,

wherein the at least first reactant comprises at least a greenhouse gas, carried by an infiltrating medium, to provide at least a first product, during which reaction a remainder of the porous matrix acts as a scaffold for facilitating the formation of the first product from the reaction mixture, thereby producing the monolithic compact maintaining the shape of the porous matrix,

wherein the monolithic compact comprises ceramic bonds,

wherein the first product comprises carbonate,

wherein the greenhouse gas is carbon dioxide, and

wherein the monolithic compact has a decomposition temperature at least about 1000°

C.

2. The monolithic compact of claim 1, wherein the monolithic compact has a decomposition temperature at least about 2000°

C.

3. The monolithic compact of claim 1, wherein the first product is produced by ion substitution, ion addition, disproportionation, or combinations thereof.

4. The monolithic compact of claim 1, wherein the first product is produced by precipitation.

5. The monolithic compact of claim 1, wherein the monolithic compact is a cement.

6. The monolithic compact of claim 1, wherein the monolithic compact comprises an interconnecting network microstructure.

7. The monolithic compact of claim 1, wherein the monolithic compact is derived from a powder.

8. A hydrothermally sintered monolithic body produced by a carbon capturing, carbon sequestering process, or a combination thereof comprising:

a porous matrix having interstitial spaces, wherein the porous matrix has a shape; and

a first product, wherein the first product is formed from a reaction between a first reactant and a portion of the porous matrix,

wherein the first reactant comprises at least a greenhouse gas and the first product is contained in at least a portion of the interstitial spaces;

wherein the porous matrix and first product form the hydrothermally sintered monolith body maintaining the shape of the porous matrix, wherein the monolithic body comprises ceramic bonds,

wherein the first product comprises carbonate,

wherein the greenhouse gas is carbon dioxide, and

wherein the monolithic compact has a decomposition temperature at least about 1000°

C.

9. The hydrothermally sintered monolithic body of claim 8, wherein the hydrothermally sintered monolithic body has a homogenous microstructure.
