Hydrothermal oxidative desulfurization of thiophene to sulfate. the effect of MoOx, WOx and carbon supports

Key Points

• The central aim is to evaluate the effect of different catalysts and carbon supports on the oxidative desulfurization of thiophene.
• Evaluated oxidative desulfurization in pressurized water
• Analyzed the role of molybdenum dioxide and oxidant ratio on sulfate formation
• Studied the impact of oxygen-rich carbon surfaces
• Sulfate formation was significantly enhanced by molybdenum dioxide, with effective oxidant ratios observed
• Oxygen-rich carbon surfaces improved the desulfurization process, contributing to higher sulfate yields
• Catalytic hydrothermal gasification was affirmed as a viable pretreatment method.
