Anatase titania-vanadium polyphosphomolybdate as an efficient and reusable nano catalyst for desulphurization of gas oil

Abstract

(Bu4N)4H[PMo10V2O40]-TiO2 nanocomposite has been synthesized by a reaction of (Bu4N)4H[PMo10V2O40] with titanium tetraisopropoxide at 100 °C via sol-gel method. The crushed nano layer of anatase phase is 20 nm in nature and fixing of (Bu4N)4H[PMo10V2O40] decreases its size. This nano Polyphosphomolybdate was shown be able to oxidative desulphurization of simulated gas oil with high S conversion (more than 98%). In the present work, efficient oxidative desulphurization of gas oil and simulated gas oil with formic acid/hydrogen peroxide system is reported. This system provides an efficient, convenient and practical method for scavenging sulfur compound.
