Torrefaction as a process for biomass conversion into biocoal
Torrefaction is a thermo-chemical treatment of biomass carried out within a temperature range from 250ºC to 300ºC, in an inert atmosphere. The process can be described as a mild form of pyrolysis. During the torrefaction process, biomass undergoes a slight breakdown and physical water (moisture) contained in biomass as well as superfluous volatiles are released while the biopolymers (cellulose, hemicelluloses and lignin) partly decompose giving off various types of volatiles. In the course of the process, the properties of biomass change and result in much better quality of fuel combustion and gassification. The final product is the remaining solid, dry, brittle, blackened material that is referred to as torrefied biomass (bio-coal) and which is more resistant to biological degradation, self-ignition and physical decomposition. This paper presents a comprehensive review of torrefaction including both advantages and disadvantages of the torrefaction process.
