We investigated the characteristics of torrefied yellow poplar (Liriodendron tulipifera) depending on reaction time (30min) and temperature (240–280°C). The thermogravimetric, grindability and calorific value of torrefied biomass were analyzed. As the torrefaction temperature increased, the carbon content of torrefied biomass increased from 49.50% to 54.42%, while the hydrogen and oxygen contents...
