The barrier and the fix

Most teams treat this as a hydroprocessing problem. It is a pyrolysis problem.

Raw bio-oil plugs, fouls and kills catalysts in continuous hydrotreaters, usually within hours. PySAF owns the step between pyrolysis and refinery.

Raw bio-oil

Refinery rejects the feed

  • Water 20–30%
  • Sugars levoglucosan
  • Oxygenates pH≈2.5, unstable
  • Metals K · Na · Ca, char

PyXCrude

Drop-in biogenic co-feed

Stabilised, low-water, low-metals feed for FCC co-processing and hydroprocessing / HEFA. No billion-dollar new builds.

  1. 01Certified biomass residues
  2. 02Fast pyrolysis (any technology)
  3. 03PySAF conditioning, the licensed step
  4. 04Refinery insertion
One biomass. Every market. PySAF process flow: certified lignocellulosic residues go through fast pyrolysis, then PySAF conditioning, branching into PyXCrude bio-crude for SAF, FCC co-processing and marine fuel, and PyXSugra sugars for bio-hydrogen, biomethane and bio-based polymers.

Products

One biomass. Two streams.

PyXCrude

Phenolic bio-crude fraction for SAF via FCC co-processing and hydroprocessing.

PyXSugra

C5/C6 sugar fraction for bio-hydrogen, biomethane and bio-based polymers.

The loop closes.PyXSugra is being developed as a bio-hydrogen feedstock, with that bio-H2 targeted as the hydrogen source for PyXCrude hydrotreatment.

Evidence · FCC co-processing

Raw oil stops at 1–2 wt%. PyXCrude targets 10–15.

Business model

We license. Partners build.

Asset-light by design: the value is the conditioning IP, the product specification, and the network from feedstock to refinery gate.

  • 01Technology licensing. Process licences for the conditioning step at partner sites.
  • 02Commercialisation. PyXCrude as a defined, tradeable intermediate.
  • 03Project development. Programmes to qualify PyXCrude unit by unit.

Demand is legislated

UK SAF Mandate

10% SAF by 2030, 22% by 2040. Obligated suppliers need eligible biogenic feed at scale.

ReFuelEU Aviation

Binding EU blending obligations from 2025, rising through 2050.

CORSIA

Global airline offsetting framework driving long-term demand for certified lower-carbon aviation fuel.

Team

Not built on a thesis. Built in reactors.

SAF, hydrogen and bio-crude development across the US and UK, from operating continuous pyrolysis reactors to refinery-ready specifications.
