Abstract
An adsorbent vessel for removing contaminants from a feed gas upstream from a cryogenic distillation process using pressure swing adsorption, temperature swing adsorption, or thermal-pressure swing adsorption. The adsorbent vessel having an adsorbent bed comprised of multiple layers of adsorbent material, including two layers of adsorbent material that selective adsorbs carbon dioxide. Each of the two layers is formed from an adsorbent material having a different capacity for adsorbing carbon dioxide.
