improving performance of the ti/sio 2 catalyst in ox idative desulfurization of refractory sulfur components with impregnation sulfate ion

Oxidative desulfurization (ods) has been promising as a substitute or complementary process fo r conventional hydrodesulfurization method because of mild reaction condition heterogeneous catalysts in ods are of interest due to the advantages of easy separation and reusability, and the a cid properties of these catalysts are very important in this work, sulfation of the ti / sio2 catalyst was studied with the aim of creating additional acid sites the results showed that despite the fact that parent catalyst was very active, sulfation coul d improve the catalyst performance because by increasing the surface acidity of the catalyst, more reactants can be absorbed it was found that temperature is a very important parameter in catalyst performance, so that the catalyst could not achi e ve to more than 45% conversion at 60 ° c
