This disclosure involves an adsorption-desorption material, e.g., crosslinked epoxy-amine material having an M w from about 500 to about 1×10 6 , a total pore volume from about 0.2 cc/g to about 2.0 cc/g, and a CO 2 adsorption capacity of at least about 0.2 millimoles CO 2 per gram of crosslinked material, and/or linear epoxy-amine material having an M w from about 160 to about 1×10 6 , a total pore volume from about 0.2 cc/g to about 2.0 cc/g, and a CO 2 adsorption capacity of at least about 0.2 millimoles CO 2 per gram of linear material. This disclosure also involves processes for preparing the crosslinked epoxy-amine materials and linear epoxy-amine materials, as well as selective removal of CO 2 and/or other acid gases from a gaseous stream using the epoxy-amine materials. |
