Torrefaction of Empty Fruit Bunch (EFB) fibres adopted in modified microwave

Abstract

Thermochemical pre-treatment process was implemented within the torrefecation temperature to improve the empty fruit bunch (EFB) fibers material, further exploiting for low rank solid energy material purposes. Modified microwave was introduced as a heat source chamber using the irradiation wavelength, with the mild exposure of atmospheric air in the system. The study involved such parameter of (i.e. heating rate and temperature) in which has influenced the process yield. Therefore, a regulated power input within 100 to 700 W was capped to access the effect toward samples and alumina crucible prepared. Based on this study, the 385 W of power selection was made with bound consideration of formation thermal shock at a constant nitrogen supply as inert gas during the heating process. The yield of compound constituents from this treatment also been discussed.
