Abstract
Torrefaction is a well-known biomass pretreatment for energy densification and preservation enhancement, but continuous industrial plants are still rare. Pelletization, a well-known energy densification process as well, can be coupled with torrefaction in order to increase both energy density and water-resistivity of pellets. This chapter presents the use of a proven innovative technology coming from the food industry for biomass torrefaction before (pre-torrefaction) and after (post-torrefaction) the pelletization step. Several biomasses (wood chips, coniferous barks, olive pips, straw, and pine pellets) have been torrefied and analyzed. The choice between pre- and post-torrefaction is finally discussed.
