Carbonate-Infused Activated Carbon for Direct Air Capture Sorbents
­Background Removal of carbon dioxide (CO2) from the atmosphere by direct air capture (DAC) can be accomplished using two chief approaches, liquid and solid. Liquid systems pass air through chemical solutions containing basic ions (e.g., hydroxide ions or bicarbonate ions), heat the resulting mixture to release the captured CO2, and then reuse the...

Electrospun K2CO3/Activated-Carbon Composites for Carbon Dioxide Capture
­Background Direct air capture (DAC) is a process of capturing carbon dioxide (CO2) directly from air. The CO2 can be captured when the air contacts a chemical medium or functionalized sorbent, and then removed from the chemical medium or functionalized sorbent to yield a CO2 stream. Invention Description Researchers at Arizona State University...

New Sorbent Types for Moisture Swing Technology
Capturing carbon dioxide from open air to minimize harmful emissions becomes less effective with lower carbon dioxide concentration. To address this, scientists use moisture swing sorbents which are chemicals that bind to carbon dioxide in dry environments and release it when exposed to moisture. Metal-organic frameworks (MOFs) contain a metal and a...

Atmospheric CO2 Enrichment and Delivery (ACED)
Microalgae are very useful biological systems for capturing carbon dioxide (CO2 ) and generating biomass and many useful products. Increasing the CO2 concentration in gas supplied to a microalgae growth system can improve its productivity many fold over using atmospheric air. Flue gas could be a good source of CO2 -enriched gas; however, its usefulness...

Carbon Dioxide Sorbents and Structures
Carbon dioxide (CO2) sequestration has had significant technological advances in recent years. Unfortunately, these methods are ineffective when the CO2 concentration is extremely low (i.e. air- capture technology). The use of humidity or moisture swing sorbents offers a distinctly different path to extracting CO2 from air. Moisture swing sorbents bind...
