Abstract: A combined torrefaction and pelletization study was performed at industrially relevant settings using a factorial design. First, wood chips of Scots pine were torrefied at high temperatures (291–315°C) and short residence times (6–12min), facilitating high throughput in a continuous pilot-scale torrefaction process. Then the torrefied materials were pelletized, also in pilot-scale, using varying moisture contents (MCs) (10–14%), sieve sizes (4–6mm), and press channel lengths (PCLs) (25 and 30mm), in all 19 batches, each of 400kg. The resulting so called black pellets exhibited bulk densities of 558–725kgm−3, durabilities of 46.3–86.5%, and fines contents of 3.8–85.8%.
