Abstract
A resin includes a functionalized aminopolymer having amine sites for capturing carbon dioxide molecules, where each aminopolymer molecule has at least one functional group amenable to crosslinking, a porogen, and a crosslinking initiator. A product includes an aminopolymer material formed into a self-supporting structure, the aminopolymer material including crosslinked aminopolymers having amine sites for the capture of carbon dioxide molecules.
Claims22
A resin, comprising:
- a functionalized aminopolymer having amine sites for capturing carbon dioxide molecules, wherein each aminopolymer molecule has at least one functional group amenable to crosslinking;
- a porogen;
- and
- a crosslinking initiator.
A product, comprising:
- an aminopolymer material formed into a self-supporting structure,
- the aminopolymer material comprising crosslinked aminopolymers having amine sites for the capture of carbon dioxide molecules.
A method of using an aminopolymer material formed as a self-supporting structure for capturing carbon dioxide gas, the method comprising:
- contacting a carbon dioxide-containing source gas with a porous aminopolymer material having amine sites for capturing carbon dioxide molecules, wherein the porous aminopolymer material is formed as the self-supporting structure;
- heating the porous aminopolymer material to a pre-defined temperature for desorbing the carbon dioxide molecules from the porous aminopolymer material;
- and
- collecting the carbon dioxide gas.
