Abstract: Crystalline support materials are provided that can serve as supports for polyamines. The support materials have a combination of properties that unexpectedly allows supported polyamines to retain an increased or maximized amount of CO2 sorption capacity after incorporation of substantial amounts of the polyamine on the support material. This combination of properties can include having a high pore volume, a high ratio of mesopore volume to micropore volume, and a sufficiently high acidity. The ability to allow supported amine sorbents to retain additional CO2 sorption capacity is unexpected. Conventionally, even when high pore volume support materials are used to support an amine sorbent, only a limited amount of the amine sorbent can be supported on the support material before substantial losses of sorbent capacity occur relative to the amount of amine sorbent.
