01 Overview
How is landfill gas upgraded with molecular sieve?
Landfill gas is cleaned of H₂S, siloxanes and VOCs, dried, and then passed through a CO₂-selective molecular sieve in a PSA or VPSA unit. Because landfill gas also contains nitrogen and oxygen drawn in from the air, a further nitrogen-rejection step may be needed to reach pipeline quality.
| CO₂ removal | CO₂ Adsorbent Molecular Sieve |
| Drying | Activated Alumina Desiccant |
| N₂ rejection | Molecular Sieve for Methane Enrichment where required |
| Process | PSA or VPSA |
| Pretreatment | H₂S, siloxane and VOC removal |
02 Challenges
What makes landfill gas harder than digester gas?
More contaminants and air ingress.
Air ingress
Nitrogen and oxygen dilute the methane.
VOCs and siloxanes
A wide range of trace compounds must be removed first.
Low methane
Methane content varies widely across a site.
Changing flow
Collection systems vary over the site’s life.
03 Solutions
Recommended setup for landfill gas
01
Power generation
Typical requirement: raise heating value for engines
- CO₂ Adsorbent Molecular Sieve — CO₂ removal

10 FAQ
Molecular Sieve for Landfill Gas Treatment FAQ
Can’t find your answer? Ask our sales engineer.
Why does landfill gas contain nitrogen?
Air is drawn into the waste mass through the collection system.
Is CO₂ removal enough for pipeline gas?
Often not; nitrogen rejection may also be needed. Molecular Sieve for Methane Enrichment removes N₂ by kinetic PSA.
What pretreatment is needed?
H₂S, siloxane and VOC removal plus drying.
Can you supply all adsorbent stages?
Yes — CO₂ adsorbent, methane-enrichment sieve and activated alumina.
