How you extract carbon dioxide from air?

Answer 1

Leave the mixture to evaporate in a contained space. The gas given off will be O2 and CO2. The O2 is lighter and more combustible. Therefore most of the CO2 will remain in the container. If necessary, you can burn off the oxygen, but it should probably just diffuse into the air. The gas remaining in the container is CO2.

Answer 2

There are several ways, but I'm still searching for an easier way. Fractional distillation of liquid air is one way. 'Scrubbers' that use a chemical that bonds to the co2 are used by submarines. At least one of these chemicals will release the co2 again when heated. Freezing air (which has had water vapour removed) to a very low temp (about -80C) can make dry ice (solid carbon dioxide). Plants remove co2 during photosynthesis. This (and water and a few other compounds) can be released again by burning.

Answer 3

The only way to remove carbon dioxide (CO2) from the atmosphere is through photosynthesis (trees and plants). If we could plant billions of trees to replace the destroyed forests that would really slow global warming.

Answer 4

Carbon dioxide can be extracted from air through a process called carbon capture, where the gas is separated from the air using various technologies such as absorption, adsorption, or membrane separation. These methods usually involve passing the air through a material that selectively captures the carbon dioxide while allowing other gases to pass through. Once captured, the carbon dioxide can be stored underground or utilized in various applications.

Answer 5

You could use micro-pore filters,

or you can cool the gases: CO2 will freeze before N2.

Answer 6

use solid absorbent-magnesium oxide absorber
