Determination of Kinetic Data for Torrefaction of Pine Bark and Maize Cane

C. Casajus, F. Marias & J.M. Legros-Adrian
Torrefaction is a mild pyrolysis process with an operating temperature included in the range 220°C­280°C. This technology, applied to ligno-cellulosic biomass, modifies its thermal properties and makes it stable, grindable and hydrophobic. It is then an interesting feedstock for high efficiency combustion and gasification. Because torrefaction mainly affects the hemicelluloses part of the incoming biomass, the associated reaction scheme and kinetics have been developed using this information (single step models, Di-Blasi and Lanzetta model and...
