Deep Oxidative Desulfurization of Model fuels by Prepared Nano TiO2 with Phosphotungstic acid

Deep Extractive Oxidative Desulfurization of Model Oil by Magnetically Recoverable Polyoxometalate-Based Nano Catalyst

Dibenzothiophene (DBT), benzothiophene (BT) and thiophene (T) were catalytically oxidized to their corresponding sulfone products by H2O2 in the presence of magnetically recoverable polyoxometalate-based nano catalyst. Different extracting solvents including ethanol, acetonitrile, and dimethylformamide were tested. The best results were obtained by ethanol extraction. The oxidative desulfurizat...

Deep Desulfurization of Transportation Fuels with Nanoreactions

Burning sulphur-laden transportation fuels results in misty and fuggy air of large cities. The combustion products of sulphur-laden fuels poison the exhaust conversion catalyst and invalidate the catalyst box. As results, the vehicle emission gets worse and worse no matter how advanced the auto technology is. Some sulphur compounds converted to sulphates after combustion and emitted into the at...

Effect of various fuels on structure and photo-catalytic activity of TiO2 nano-crystalline prepared by microwave-assisted combustion method

Nano-crystalline TiO2 were synthesized by combustion method using metal nitrate solution and urea, glycin and citric acid fuels. Microwave irradiation was used as heating source. X-ray diffraction, scanning electron microscope as well as Fourier transform infrared spectroscopy were performed to characterize the obtained samples. X-ray diffraction patterns revealed that in the case of citric aci...

Synthesis and Characterization of Ordered Mesoporous Silica Pillared Clay with HPW Heteropoly Acid Encapsulated into the Framework and Its Catalytic Performance for Deep Oxidative Desulfurization of Fuels

Biocatalytic desulfurization (BDS) of petrodiesel fuels.

Oil refineries are facing many challenges, including heavier crude oils, increased fuel quality standards, and a need to reduce air pollution emissions. Global society is stepping on the road to zero-sulfur fuel, with only differences in the starting point of sulfur level and rate reduction of sulfur content between different countries. Hydrodesulfurization (HDS) is the most common technology u...
