Airex Energy, Laval, QC

Airex Energy has successfully developed an exciting new technology for biomass torrefaction. Based on a unique patented cyclonic bed reactor, CarbonFX enables large scale biocoal production from a variety of feedstock, including woody biomass and agricultural waste. Torrefaction, a mild form of pyrolysis, refers to the heat-treatment of biomass at 250-320 °C with little or no oxygen present. The purpose of torrefaction is to remove moisture and VOCs (volatile organic compounds) from raw biomass, thus converting it to a solid, blackened, hydrophobic (water-resistant) material. The final product, known as torrefied biomass or biocoal, typically contains 70% of the mass and 90% of the energy content of the pre-treated material.
