Abstract
Methods of sorbing carbon dioxide on porous, hydrolyzed divinylbenzene/maleic anhydride polymeric sorbents are provided. Additionally, compositions resulting from sorbing carbon dioxide on porous, hydrolyzed divinylbenzene/maleic anhydride polymeric sorbents are provided. The porous polymeric sorbents typically have micropores, mesopores, or a combination thereof and can selectively remove carbon dioxide from other gases such as methane or hydrogen.
Claims15
A method of sorbing carbon dioxide on a porous polymeric sorbent, the method comprising:
- providing the porous polymeric sorbent, wherein the porous polymeric sorbent has a BET specific surface area equal to at least 250 m2/gram, the porous polymeric sorbent comprising
- (a) 8 to 40 weight percent of a first monomeric unit of Formula (I);
- (b) 48 to 75 weight percent of a second monomeric unit of Formula (II);
- (c) 0 to 20 weight percent of a third monomeric unit of Formula (III) wherein R1 is hydrogen or alkyl;
- and
- (d) 0 to 8 weight percent of a fourth monomeric unit of Formula (IV);
- exposing the porous polymeric sorbent to a gas mixture comprising carbon dioxide;
- and sorbing carbon dioxide on the porous polymeric sorbent.
