Concept project — design demonstration, not a live business.

Purefield

Technology

Advanced MOF-based gas purification, built for real-world deployment.

Our Approach

Purefield develops metal-organic framework (MOF) adsorbents optimized for selective gas capture. Our materials target sulfur compounds like H₂S with high efficiency while allowing methane and other valuable gases to pass through.

Combined with modular hardware, our technology enables on-site biogas upgrading with minimal footprint and low energy consumption.

MOF Media

MOF Media

Engineered porous materials with tunable selectivity for targeted gas capture.

  • High surface area for maximum adsorption capacity
  • Selective binding sites for H₂S over CH₄
  • Stable performance across varying conditions
Modular System

Modular System

Fixed-bed adsorption columns designed for easy deployment and operation.

  • Swappable cartridge design for minimal downtime
  • Scalable from pilot to full-scale installations
  • Compatible with existing biogas infrastructure

How It Works

1

Input

Raw biogas enters the adsorber

2

Capture

MOF media captures H₂S (and CO₂)

3

Output

Purified biomethane exits

The MOF media can be regenerated at low temperatures, enabling continuous operation.

Regeneration Advantage

Unlike disposable media, our MOF can be regenerated multiple times.

  • Low-temperature regeneration reduces energy costs
  • Designed for extended cycle life
  • Significantly lower lifetime media costs
