Torrefaction processes of three kinds of waste biomass species, including EFB(Empty Fruit Bunches), wood pellet and rice husks were investigated on the pilot scale of torrefaction reaction system with rotary kiln type of reactor. The yield of torrefied material from EFB(61.0 wt%) and waste pellet(76.7 wt%) was higher than that of gas and liquid, while only 30.8 wt% of torriefied rice husks was obtained. Especially, the energy density of torrefied material with respect to waste biomass species is following order; rice husks ≈ EFB > wood pellet. In addition, O/C and H/C for EFB and Rice husks after torrefaction reaction was similar with that of coal, while wood pellet was affected slightly. It is mainly related to the lignocelluloses components in waste biomass materials. From this result, we concluded that the torrefied EFB is more suitable to coal-firing power plant compared to rice husks and wood pellet.
