Abstract : Bio-waste materials were used as a potential adsorbent for non-conventional techniques for sulfur recovery from heavy fuel oil (HFO). Different forms of date palm kernel powder (DPKP) are used as potential adsorbents. Five forms were used: DPKP without any treatment, carbonized DPKP (CDPKP), acid activated CDPKP (AACDPKP), ZnCl2 activated DPKP (ZnCl2 DPKP), and ZnCl2 activated carbonized DPKP (ZnCl2 CDPKP). The extractive-adsorptive desulfurization technique was applied with different solvents at different operating conditions of temperatures and solvent to oil ratios. This work was achieved to optimize the best operating conditions for the highest sulfur recovery and proper physical properties of the resulting product. It was found that the carbonized DPKP activated by ZnCl2 had the highest performance in reducing sulfur content from HFO using methyl ethyl ketone (MEK) with 3:1 solvent to oil ratio over two hours of contact time. Sulfur recovery was increased to 45.85% when the adsorption operating temperature was increased to 50oC. This process was able to improve the carbon residue, ash content, asphaltene content, and heavy metals removal. This improvement has a positive significant environmental impact on the emission of harmful materials to the atmosphere and improves the performance of the engines and machinery.
