Question

I would like to see if I could make my own concentrated CO2

by separating it from my own exhaled breath. I would also love to see if I could pressurize it so I could make my own carbonated water!

When you exhale, the gas that comes out of your mouth contains 78% nitrogen, 17% oxygen, 4% carbon dioxide and 1% other gases
Is there any existing procedure for separating carbon dioxide from breathing air? I have done some research, but I have only found (industrial-scale) methods for separating nitrogen.

Answer 1

Yes, there are procedures for separating carbon dioxide from breathing air. One common method is through a process called carbon capture and storage (CCS). Another method is through a process called adsorption.

Step-by-step explanation:

Yes, there are procedures for separating carbon dioxide from breathing air. One common method is through a process called carbon capture and storage (CCS), which is used on an industrial scale to capture CO2 emissions from power plants and other sources.

Another method is through a process called adsorption, where porous materials like activated carbon or zeolites are used to selectively adsorb CO2 molecules from a gas mixture.

To pressurize the separated CO2 and make carbonated water at home, you can use a carbonation system that infuses CO2 gas into water under pressure. These systems typically use food-grade CO2 cylinders and a carbonation unit that allows you to control the level of carbonation in the water.
