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.

- 21. 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 to undergo a reaction with at least a first reactant carried by a 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 a monolithic compact.

42. A hydrothermally sintered monolithic body produced by a carbon capturing, carbon sequestering process, or a combination thereof comprising:
-
a porous matrix having interstitial spaces; and a first product, wherein the first product is formed from a reaction between a first reactant and a portion of the porous matrix, and wherein the first product is contained in at least a portion of the interstitial spaces; and wherein the porous matrix and first product form the hydrothermally sintered monolith body.
