Biomass waste are attractive energy source that can combat the rising energy challenge facing the world when utilized appropriately and accordingly. Unfortunately, the knowledge of the potential of some biomass waste are still missing and this has affected their maximum utilization as energy source in thermal processes like gasification. In this study, the potential of palm oil decanter cake (PODC) for syngas production through thermal processes was determined by bomb calorimeter, CHNS analyzer, Thermogravimetric analysis (TGA), Scanning Electron Microscopy and Energy Dispersive Spectroscopy (SEM-EDS) and X-ray Fluorescence (XRF). Bomb calorimeter revealed the energy value as 17.40 MJ/Kg. CHNS revealed the amount of C, H, N, S and O as 41.41 , 5.92 , 5.31 , 0.30 and 47.06 respectively. TGA revealed the presence of volatile matter, fixed carbon and ash content as 58.38 , 4.91 and 31.16 respectively. SEM-EDS revealed the dominant presence of carbon (74.80 ). XRF revealed SiO2 (28.60 ) and CaO (22.70 ) as the dominant oxides and the presence of bed materials like Al2O3 (6.54 ), MgO (2.76 ), CaO (22.70 ) and Fe2O3 (7.49 ) which serve as resistance to ash deposition problems during thermal processes. Overall, PODC show likely potential of being used as fuel for syngas production through thermal processes. © 2023, AIDIC Servizi S.r.l.
