Abstract:
Today, energy from biomass is promoted as part of possible solutions to the rarefaction of fossil energy and to global warning. Followed by a Fisher-Tropsch synthesis, biomass gasification is a possible way to produce biofuels. Nevertheless, a preconditioning is needed, since the physicochemical properties of the raw biomass are not suitable for a direct use a gasifier. Torrefaction is among possible pretreatments. This presentation is more specifically focused on the mechanical modification of torrefied wood which is one of the major sources of biomass that can be used. In this work, the loss of mechanical properties caused by torrefaction was first evaluated using low compression rates. However, to be closer to the grinding conditions, an impact device was specially conceived to evaluate the mechanical behavior of wood at high compression rates. Our results show that the loss of mechanical strength caused by the torrefaction improves its grindability and eases its transformation into small particles, suitable to be injected into a gasifier.
