Oxidative Desulfurization of Gas Condensate Using Graphene Oxide Supported Molybdenum Sulfide Nanocatalyst

In this study, molybdenum sulfide nanocatalyst supported graphene oxide was synthesized by ultrasonic method and was used for oxidative desulfurization of gas condensate with initial sulfur content of 2850 ppm. The nanocatalyst was evaluated using XRD, BET, TPD, XPS, Raman spectroscopy and reactor tests. The results showed that M9-GOnanocatalyst with 9%by weight of molybdenum metal, 98% desulfurization yield of gas condensate in operation conditions (7500C, oxidative agent 3%, and reaction time 90 min with acetonitrile solvent) was obtained.  M9-GO catalyst also showed good activity and stability after nine step, recovery after extraction-oxidation reaction. Also, the effect of surface area, pore diameter and catalyst acidity on the performance of oxidative desulfurization activity has been investigated. The results showed that the higher the surface area, porosity, and catalyst acidity, the higher the efficiency of oxidative desulfurization process.
