Abstract
The present disclosure provides for sorbents and contactors, methods of using sorbents and contactors to capture CO2, structures including the sorbent, and systems and devices using sorbents and contactors to capture CO2. In an aspect, the present disclosure provides for sorbents that include a CO2-philic phase and a support. The present disclosure provides for sorbents and contactors that include a CO2-philic phase and a support, where the CO2-philic phase includes a modified amine polymer that is the reaction product of an amine and an aziridine or azetidine
Claims23
A composition comprising:
- a CO2-philic phase, wherein the CO2-philic phase includes a reaction product of an amine and an aziridine or azetidine, wherein the reaction product has a molecular weight of 200 to 5,000 g/mol.
14-15. (canceled)
A system for capturing CO2 from a gas, the system comprising:
- a first device configured to introduce the gas to a sorbent to bind CO2 to the sorbent, wherein the sorbent comprises a CO2-philic phase, wherein the CO2-philic phase includes a reaction product of an amine and an aziridine or azetidine, and wherein the reaction product has a molecular weight of 200 to 5,000 g/mol;
- a second device configured to heat the sorbent containing the bound CO2 to at least a first temperature to release the bound CO2;
- and
- a third device configured to collect the released CO2.
