Effect of Torrefaction on Palm Oil Waste Chemical Properties and Kinetic Parameter Estimation

In Malaysia, palm oil wastes are identified as the potential biomass for renewable energy sources. However, biomass is more challenging to utilise as compared to coal. Usually palm oil wastes suffer from a low heating value, low bulk density and their ability to absorb moisture from the surroundin...
