Abstract:
This disclosure involves an adsorption-desorption material, e.g., crosslinked polyvinyl-amine material having an Mw from about 500 to about 1×106, total pore volume from about 0.2 cc/g to about 2.0 cc/g, and a CO2 adsorption capacity of at least about 0.2 millimoles per gram of crosslinked material, and/or linear polyvinyl-amine material having an Mw from about 160 to about 1×106, total pore volume from about 0.2 cc/g to about 2.0 cc/g, and a CO2 adsorption capacity of at least about 0.2 millimoles per gram of linear material. This disclosure also involves processes for preparing the crosslinked polyvinyl-amine materials and linear polyvinyl-amine materials, as well as selective removal of CO2 and/or other acid gases from a gaseous stream using the polyvinyl-amine materials.
