Torrefaction is the thermal treatment techniques performed at relatively low temperature (< 300 °C) in an inert atmosphere, which aims to improve the fuel properties attractively. In this study, woody biomass (Leucaena leucocephala) was torrefied at various temperatures and holding times and the pyrolysis behaviors of the torrefied wood was examined in detail by using TG­MS technique. It was found that the carbon content and the calorific value of the torrefied leucaena increased significantly when...
