Samenvatting:
Biomass is expected to play a major role in the transition to sustainable energy production.
However, biomass is a difficult fuel and most thermal conversion processes have very stringent
fuel specifications. Torrefaction offers the potential to convert biomass into attractive solid
biofuels. It involves heating in the absence of oxygen to a temperature of 200 to 300 °C. As a
result, biomass becomes easy to grind and water resistant, reducing the risk of spontaneous
biological degradation and heating, and permitting outdoor storage. By combining torrefaction
with pelletisation, biomass is converted into a high-energy-density solid bioenergy carrier with
superior properties in view of (long-distance) transport, handling and storage, and in many
major end-use applications (e.g., co-firing in coal-fired power stations and gasification-based
biofuels and biochemicals production).
