Abstract:
In this study, Ni-Mo/rGO catalysts synthesized using incipient wetness impregnation (IWI) method and then calcination process. Citric acid (CA) used as a chelating agent. Different catalysts prepared and characterized through the XRD, ICP and FTIR analyses. Ability of the synthesized catalyst in an oxidative desulfurization (ODS) process of a model feed was examined. Here dibenzothiofene used in n-decane as a model feed. Due to environmental considerations, from amongst different oxidants hydrogen peroxide was chosen as an oxidizing agent. All stages of synthesis and reactor test designed utilizing the Design Expert software. Three parameters including the; temperature, oxidant to substrate molar ratio and catalyst to substrate molar ratio were investigated in order to determine the optimum conditions toward reactor evaluations. Results showed that the synthesized catalysts possessed significant ability to perform the ODS process such that; 99% conversion during 60 min of the process duration was achieved using the Ni-Mo (20)/rGO catalyst.
