Development of Kinetics Model for Torrefaction of Empty Fruit Bunch from Palm Oil Waste

Torrefaction is a thermal conversion method widely used for enhancing the properties of biomass. Usually this process is conducted under an inert atmosphere within a temperature range of 200 °C – 300 °C with residence time up to 60 minutes. During the torrefaction process, biomass is thermally decom...
