PyroFriction™
TECHNOLOGY
 

The PyroFriction™ is a friction-based pyrolysis process. By utilizing friction turbines—cavitation pumps—heat is generated through the combined effects of friction and cavitation, maintaining the measurable process temperature at only 300–350°C.
The process is conducted entirely in the liquid phase, ensuring rapid and uniform energy transfer to biomass particles, which is essential for efficient fast pyrolysis.

The actual temperature directly on the biomass surface is several dozen degrees higher due to friction and cavitation, where vapor bubbles form and collapse violently within the liquid. Thanks to the specialized design of the friction turbines, these implosions do not occur on the rotor components but instead take place directly in the zone where the biomass is mixed with the liquid carrier. The implosion of these bubbles generates microscopic shock waves and pressure pulses, which increase the local process temperature and enhance and accelerate the overall pyrolysis process.

We can process any type of forest or agricultural biomass (straw, sawdust, nut shells, sunflower husk, etc.), and by using small amounts of catalysts—which often occur naturally in the feedstock—we can accelerate the process and produce higher-quality products.
