In this study, the possibility of direct desulfurization technology as a pretreatment technology to reduce the concentration of sulfur compounds contained in syngas produced from the gasification of petroleum coke was experimentally investigated. High-temperature thermal treatment and solvent extraction were applied as direct desulfurization techniques for petroleum cokes. The weight changes due to volatilization of free sulfur above 250 °C was confirmed by TGA analysis. When the thermal treatment of petroleum coke powder was performed in the range of 250-330 °C, sulfur volatilization with high yield above 330 °C was confirmed by SEM / EDX analysis. In addition, it was confirmed by UV-Visible adsorption spectrum and FT-IR analysis that organic sulfur contained in petroleum coke was extracted with using ethanol, acetone, and polyethylene glycol as solvents. Although the effect of direct desulfurization is not high by thermal treatment and solvent extraction, it was considered to be effective as a pretreatment method to reduce the concentration load of sulfur compound gases in syngas produced from petroleum cokes derived gasification. In the future, it was expected to contribute to the expansion of mass hydrogen production technology by developing a pretreatment process technology to reduce sulfur content in petroleum coke by direct desulfurization.
