An adsorption-desorption material, in particular, crosslinked organo-amine polymeric materials 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 an adsorption capacity of at least about 0.2 millimoles adsorbed CO 2 per gram of adsorption-desorption material, and linear organo-amine polymeric materials 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 an adsorption capacity of at least about 0.2 millimoles adsorbed CO 2 per gram of adsorption-desorption material. This disclosure also relates to processes for preparing the crosslinked and linear organo-amine materials, as well as to selective removal of CO 2 and/or other acid gases from a gaseous stream using the adsorption-desorption materials. |
