In this study, torrefaction was performed using cedar and fibrous biomass, and the higher heating value was measured. Visualization experiments and TG measurements were also conducted to investigate the behavior of the samples during the torrefaction process. The results showed that the char yield decreased as the torrefaction temperature increased, and that there were differences between the yields of cedar and fibrous biomass due to the components contained in the samples. The HHV of both samples increased as the torrefaction temperature increased, and the HHV of cedar was comparable to that of coal at the set temperature of 573 K. In the visualization experiment, the volume of both samples expanded just before the organic matter generated during torrefaction was released from the inside to the outside, and the mass of both samples decreased at the same time.
