<p>Collecting carbon dioxide contained in a gas, comprises contacting gas with a carbon dioxide adsorbing material. The material includes an amine impregnated on a porous solid support and has a moderated affinity for carbon dioxide such that it has an adsorption constant of 1-50 bar ->1 at 348 K when the material has an adsorption isotherm approximated by a model of Langmuir. Collecting carbon dioxide contained in a gas, comprises contacting gas with a carbon dioxide adsorbing material. The material includes an amine impregnated on a porous solid support and has a moderated affinity for carbon dioxide such that it has an adsorption constant of 1-50 bar ->1 at 348 K when the material has an adsorption isotherm approximated by a model of Langmuir according to an equation of q a d s = q s a t(b.p/1+b.p), where q a d s is carbon dioxide concentration in adsorbed phase, q s a t is saturation capacity, and p is partial pressure of carbon dioxide.</p> |
