Fischer-Tropsch technology
Fischer-Tropsch technology converts synthesis gas (hydrogen and carbon monoxide) into liquid hydrocarbons that are refined into sustainable aviation fuel, renewable diesel, and synthetic fuels.
Velocys licenses advanced Fischer–Tropsch technology designed for commercial-scale sustainable fuel production.
Quick answers on this page
What is Fischer–Tropsch technology?
Fischer–Tropsch (FT) technology is a catalytic process that transforms syngas into synthetic hydrocarbons through controlled chain-growth reactions.
Originally developed in the 1920s, FT technology is now used globally to produce drop-in fuels from:
- Biomass
- Municipal waste
- Biogas
- Renewable hydrogen and captured CO₂
The output of the process, often called FT synthetic crude, is upgraded into finished transportation fuels.
How does Fischer-Tropsch technology work?
Fischer-Tropsch synthesis converts carbon monoxide and hydrogen into hydrocarbons over a metal catalyst at elevated temperature and pressure.
The process involves:
- Syngas production
- Catalytic FT synthesis
- Product upgrading
The reaction forms long-chain paraffinic hydrocarbons suitable for refining into sustainable aviation fuel and renewable diesel.

Why is reactor design important in Fischer–Tropsch technology?
Fischer-Tropsch reactions are highly exothermic, requiring precise temperature control to maintain product selectivity and catalyst stability.
Reactor configuration directly influences:
- Fuel yield
- Plant size
- Capital cost
- Operational stability
Velocys uses microchannel reactor architecture to improve heat management and volumetric productivity.
See detailed engineering on the Fischer–Tropsch reactor page.
Why is catalyst performance critical?
The catalyst determines reaction rate, selectivity, and overall fuel yield in Fischer–Tropsch synthesis.
Catalyst characteristics influence:
- Chain growth probability
- Product distribution
- Conversion efficiency
- Catalyst lifetime
Velocys’ proprietary catalyst is engineered to integrate with its microchannel reactor design.

What fuels are produced using Fischer–Tropsch technology?
Fischer–Tropsch technology produces synthetic hydrocarbons that are upgraded into drop-in fuels compatible with existing engines.
Primary products include:
- Sustainable aviation fuel (FT synthetic paraffinic kerosene)
- Renewable diesel
- Synthetic marine fuels
- eFuels

Frequently asked questions
What is the main output of the Fischer-Tropsch process?
Synthetic hydrocarbons (FT syncrude) that are upgraded into SAF, renewable diesel, and other fuels.
What is FT-SPK?
Fischer-Tropsch Synthetic Paraffinic Kerosene — an ASTM-approved blending component for aviation fuel.
Why is temperature control important in FT reactors?
FT synthesis is highly exothermic. Poor heat management reduces selectivity and catalyst life. Microchannel reactors improve heat removal and maintain stable reaction conditions.
Can Fischer-Tropsch technology produce eFuels?
Yes. When syngas is derived from renewable hydrogen and captured CO₂, FT synthesis produces synthetic eFuels suitable for aviation and heavy transport.
How does Velocys reduce SAF production cost?
By increasing volumetric productivity, improving yield, reducing reactor footprint, standardizing modules, and offering a licensable, repeatable technology package.
