Torrefaction of pine wood in a continuous system and optimization of torrefaction conditions
International Journal of Energy Research, 2018 Red pine wood particles were torrefied in a screw conveyor reactor system continuously having a capacity of 5 kg/hour. During torrefaction, operating conditions were very important. Changes in the reactor temperature and the reactor residence times had large influences on product yields. With increasing torrefaction temperature, the volatile matter and
