Very few studies have been reported
in the literature on how to make torrefied sawdust into
torrefied pellets, following the same procedures as making regular
wood pellets from raw sawdust. In this study, we carried out a systematic
study on producing torrefied sawdust from a bubbling fluidized
bed reactor and then making the torrefied sawdust into
torrefied pellets in a single die compression test unit.
