Abstract
A method of separating carbon dioxide (CO) from air, where the method includes: feeding air into a cooler to generate cooled air, the cooled air including nitrogen (N), oxygen (O), water (HO), and CO; feeding the cooled air to a first adsorption column including a first zeolite adsorbent to selectively capture the HO from the cooled air, generating dried cooled air; and feeding the dried cooled air to a second adsorption column including a second zeolite adsorbent to selectively capture the COfrom the dried cooled air, generating a tail gas, wherein the second zeolite adsorbent includes a Linde Type A (LTA) aluminosilicate zeolite that is hydrolyzed and at least partially collapsed.
