Abstract: The invention relates to regenerative, solid sorbents for adsorbing carbon dioxide from a gas mixture, including air, with the sorbent including a modified polyamine and a solid support. The modified polyamine is the reaction product of an amine and an epoxide. The sorbent provides structural integrity, as well as high selectivity and increased capacity for efficiently capturing carbon dioxide from gas mixtures, including the air. The sorbent is regenerative, and can be used through multiple cycles of adsorption-desorption.

Abstract: The invention relates to regenerative, solid sorbent for adsorbing carbon dioxide from a gas mixture, with the sorbent including a modified polyamine and a nano-structured solid support. The modified polyamine is the reaction product of an amine and an aldehyde. The sorbent provides structural integrity, as well as high selectivity and increased capacity for efficiently capturing carbon dioxide from gas mixtures, including the air. The sorbent is regenerative, and can be used through multiple operations of absorption-desorption cycles.

Abstract: A method for producing methanol from a methane source such as methane from natural (shale) gas by first reacting one equivalent of methane with oxygen from the air to result in complete combustion to produce carbon dioxide and water in a molar ratio of 1:2; then conducting a bi-reforming process with a mixture of methane: carbon dioxide:water having a ratio of 3:1:2 to produce metgas, a mixture of hydrogen and carbon monoxide having a molar ratio of 2:1 to 2.1:1; and finally converting metgas exclusively to methanol. The thus produced methanol can be dehydrated to form dimethyl ether, with water produced being recycled back to the bi-reforming process, if necessary.

Abstract: A method of producing methanol from shale gas and CO2 by the exclusive dry CO2 fracking of shale rock by injection of gaseous CO2 at a pressure between 10 and 100 atm to extract shale gas and recover it together with used CO2; combining and admixing produced shale gas containing CO2 and steam to produce a mixture of methane:carbon dioxide:water having a molar ratio of 3:1:2 for conducting the bi-reforming reaction to form a mixture of hydrogen and carbon monoxide having a molar ratio of 2:1 to 2.1:1; and converting the hydrogen and carbon monoxide under conditions sufficient to exclusively form methanol.
