    Empty fruit bunch (EFB) are the second-highest waste produced in the oil palm industry which is 18 022 tonnes in a year. However, the presence of oil palm waste especially from empty fruit bunch (EFB) give a major problem to the disposal. Herein, EFB waste has been identified as a potential carbon source for synthetic graphite production. This is due to implement the lower heating temperature of synthetic graphite produced in controlled heating conditions. Several parameters have been manipulated to study the effect of various parameters on the graphitization process. Hence, in this study, the effect of soaking time towards graphitization of empty fruit bunch (EFB) waste has been investigated. EFB waste was heat treated with various soaking times which is 2 hours, 2.5 hours and 3 hours in controlled heating conditions with constant heating temperature at 500°C and heating rate at 10°/minute After heating treatment, the samples were characterized using X-ray Diffraction (XRD) and analyzed by X'Pert Highscore Plus software. The functional group of synthetic graphite was determined by using Fourier Transform Infrared spectroscopy (FTIR). The morphological study was carried out by using Scanning Electron Microscope (SEM). From the analysis, the best synthetic graphite produced is at the 2.5 hours soaking time with a constant heating temperature at 500°C and a constant heating rate at 10°/min.

    Synthetic graphite was synthesized from oil palm trunk chip in controlled heating condition or pyrolysis process. The soaking time was varied in the range of 2.5 hours, 3 hours, and 3.5 hours. While the heating rate and heating temperature was constant at 20 °/min and 500°C accordingly. After heat treatment process, the samples were characterized by X-Ray Diffraction (XRD) and analyzed using X'Pert Highscore Plus software. Synthetic graphite phase was analyzed by XRD and it was further supported by Fourier Transform Infrared (FTIR) Spectroscopy analysis to verify existence of functional group. The morphological study was carried out by using Scanning Electron Microscope (SEM). Based on the analysis, it was confirmed that synthetic graphite was successfully synthesized at 3hours soaking time with 500 °C and 20 °/min heating rate. Synthetic graphite was observed in the form of amorphous carbon based on the XRD diffraction pattern that match with the reference code of 00-041-1487.

    Synthetic graphite was produced from oil palm trunk chip in lower heating temperature via pyrolysis process. The heating rate (10 °/min and 20 °/min) were varied whilst the heating temperature at 500 °C was fixed. All of the samples produced after heat treatment process were characterized by X-Ray Diffraction (XRD) and the diffraction pattern obtained analyzed using X’Pert Highscore Plus software to affirm the phase analysis. To ensure the graphitic nature of synthetic graphite produced, RAMAN analysis was conducted. Morphological study of the synthetic graphite produced involved scanning electron microscope (SEM) analysis. From the investigation, the results show, confirmation that synthetic graphite was successfully synthesized at the heat treatment of 500 °C (20 °/min heating rate) with fixed soaking hours. Synthetic graphite produced matched with XRD reference code of 00-041-1487. Analysis of RAMAN confirm the formation of D, G and 2D peaks at the respective wavenumber of 1250 cm-1, 1625 cm-1 and 2700cm-1.
