Torrefaction
Biomass is wet and bulky
Biomass sources are distributed
Pretreatment required!
• Friable and less fibrous
• Hydrophobic
Torrefaction process
• Preserved
• Reduced contaminations
• Homogeneous
On-site preparation of biomass by drying, milling and
Higher heating value
torrefaction (no external energy• requirement)
Torrefaction: roasting of biomass at 250°C
