Abstract:

Torrefaction process transforms biomass in a more valuable product reducing transportation, storage and milling costs. Advantages of the improved fuel can pay back for the production costs in applications with large biomass consumptions which require long transport distances and / or applications which require very fine biomass pulverization. Some examples of these applications are: biomass cofiring in coal power plants, second generation biofuels production and pellet production for international trade. Torrefaction is based on the slow heating of biomass up to 230­300ºC in an oxygen free atmosphere. Reactions involved in the process generate changes in the biomass structure reducing the fiber content and increasing the low heating value. Power consumption for milling torrefied biomass is decreased and after pelletization the energy density of the fuel is increased considerably. Additionally, torrefied biomass is more hydrophobic assuring constant low moisture content, more homogeneous and more resistant to biological degradation. Due to the clear interest of the process, CENER has built a new pilot plant for biomass torrefaction with a capacity to process up to 500 kg/h. In this paper a description of the pilot plant and proposed torrefaction process are presented.
