ABSTRACT Fossil fuels are running low and are expected to run out, so the world needs renewable energy. Biomass from Empty Fruit Bunches (EFB) is one of the potential renewable energy. In previous studies, peat water was used to reduce potassium (K) so that potassium oxide (K2O) decreased which can cause slagging and fouling, and torrefaction methods to increase the heating value. Chlorine cau…
