01 Overview
Which adsorbent is used for CO₂ capture by VPSA?
Adsorption-based CO₂ capture uses a CO₂-selective 13X-type molecular sieve in a vacuum pressure swing adsorption (VPSA) unit. The sieve adsorbs CO₂ from dried process or flue gas and releases it when vacuum is applied, producing a CO₂-rich stream for use or storage.
| Main adsorbent | CO₂ Adsorbent Molecular Sieve |
| Alternative | 13X Molecular Sieve |
| Feed drying | Activated Alumina Desiccant |
| Process | VPSA |
| Feeds | Dried process gas, flue gas, hydrogen plant tail gas |
02 Challenges
What limits adsorption-based capture?
Capture units must handle large, wet, dilute streams.
Water in the feed
Water must be removed first or it displaces CO₂.
Dilute CO₂
Low CO₂ partial pressure needs high-selectivity adsorbents.
Energy use
Vacuum pumps dominate operating cost.
Impurities
SOₓ and NOₓ can degrade adsorbents.
03 Solutions
Recommended setup for CO₂ capture
01
Process gas capture
Typical requirement: CO₂ from hydrogen, syngas or biogas streams

- Activated Alumina Desiccant — drying layer
02
Flue gas capture
Typical requirement: CO₂ from dried flue gas
- CO₂ Adsorbent Molecular Sieve — CO₂ adsorption
- 13X Molecular Sieve — high-capacity alternative
03
Pilot and R&D units
Typical requirement: test adsorbents at small scale
- CO₂ Adsorbent Molecular Sieve — samples from 5–10 kg

Why must the gas be dried?
Water is held more strongly than CO₂ on zeolites and reduces capture capacity.
VPSA or TSA?
VPSA regenerates by vacuum without heating; TSA uses heat. The choice depends on the plant.
Can you supply pilot quantities?
Yes, samples from 5–10 kg.
Is the sieve affected by SOₓ?
Acid gases can degrade zeolites; remove them upstream.
