Abstract
Palm oil solid waste that is relatively easy to find is empty fruit bunches (EFB). EFB biomass is converted into pellets to get a uniform size, then heated through torrefaction into bioenergy so that its utilization is more optimal and can increase economic value. Torrefaction was carried out using an electric furnace with a target temperature of 280oC and a duration of 20 minutes. The purpose of this paper is to determine the effect of torrefaction on the chemical properties of EFB pellets. The results of this study are hemicellulose and cellulose decreased by 0.58% - 0.77%, this happens because hemicellulose and cellulose are degraded with increasing temperature and time of torrefaction. This is confirmed by changes in the line spectrum for FT-IR analysis where C-O, C=C, C-H, and O-H experience changes in the line spectrum that indicate changes in chemical composition. Lignin increased after torrefaction by 2.71%. Water content in EFB pellets decreased by 0.65%, while EFB pellets without treatment (control) by 14.95% after torrefaction became 22.70%. The volatile content of EFB control pellets was 69.55% after torrefaction to 61,21% so that the fixed carbon content of EFB control pellets was 10.03% and EFB pellets after torrefaction became 14.23%. The heat value of EFB pellets before torrefaction is 15.82 MJ/kg, and after torrefaction, the heating value increases to 18.28 MJ/kg so that it reaches the standard requirements of SNI 8675: 2018 as biomass pellets. Torrefaction pellets from EFB can provide a large increase in the quality of the bioenergy chemical properties. Biomass torrefaction is very suitable for combustion in power plants and home industries.
