Abstract
The present invention describes methods and systems for extracting, capturing, reducing, storing, sequestering, or disposing of carbon dioxide (CO2), particularly from the air. The CO2 extraction methods and systems involve the use of chemical processes, mineral sequestration, and solid and liquid sorbents. Methods are also described for extracting and/or capturing CO2 via condensation on solid surfaces at low temperature.
Claims13
A method for extracting, capturing, or sequestering carbon dioxide from air, comprising:
- (a) exposing the air to a solid sorbent material comprising a large absorption surface so as to saturate the sorbent material with carbon dioxide;
- (b) removing remnant air from the saturated sorbent material under reduced pressure;
- (c) condensing the carbon dioxide onto a cold surface to capture the carbon dioxide in solid form;
- and
- (d) releasing the captured carbon dioxide to a system for collection, storage, or transport.
