−The current technologies for achieving low sulfur in diesel fuel are based on hydrotreating, which requires high temperature, high pressure and excessive supply of hydrogen. Oxidative desulfurization (ODS) is considered one of the promising new methods for super deep desulfurization, which could be carried out under very mild conditions (atmospheric pressure, <100 oC) without consumption of hy...

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...

Inexpensive and low-viscosity Protic Acidic Ionic Liquids (PAILs) of N-metheyl-2-pyrrolidone formate, acetate, and propionate abbreviated as [Hnmp][HCOO], [Hnmp][CH3COO] and [Hnmp][CH3CH2COO] respectively, were prepared and characterized by FT-IR and H-NMR. Deep oxidative and extractive desulfurization of a simulated oil and a real diesel containing 1000 ppm...

A novel AgO/ZnO/HY-zeolite bimetallic nanocatalyst was designed and synthesized by an impregnation method. The purpose of this to remove dibenzothiophene as the primary sulfur content from a model light gasoil in catalytic oxidative desulfurization (ODS) process. characteristics were determined Fourier transform IR spectroscopy, Brunauer-Emmett-Teller analysis, scanning electron microscopy, X-r...

Sulfur (S) and nitrogen (N) are elements naturally found in petroleum-based fuels. S- N-based compounds liquid fuels associated with a series of health environmental issues. Thus, legislation has become stricter worldwide regarding their content related emissions. Traditional treatment systems (namely hydrodesulfurization hydrodenitrogenation) fail to achieve the desired levels S N contents wit...

To prepare ultra-clean gasoline fuel, a new nanocomposite TBA-PV2Mo10@PVA was introduced as an efficient and green catalyst for oxidative desulfurization (ODS) process. The nanocomposite was successfully prepared by reaction of tetrabutylammonium bromide (TBA), H5PMo10V2O40, and poly vinyl alcohol (PVA) at room temperature via sol–gel method under oil-bath condition. The synthesized TBA-PV2Mo10...

Catalytic oxidative desulfurization (ODS) of fuel oils is considered one the most promising non-hydrodesulfurization technologies due to advantages mild reaction conditions, low cost and easy removal aromatic sulfur compounds. Based on this reason, preparation highly efficient ODS catalysts has been a hot research topic in field. Recently, metal-organic frameworks (MOFs) have attracted extensiv...

In-situ synthesis of Ti-incorporated MCM-41 nano catalyst was carried out by the hydrothermal method to prepare a mesoporous catalyst for the oxidative desulfurization reaction (ODS). Oxidative reaction of dibenzothiophene (DBT) as a heavy sulfur compound was evaluated in a solution of n-decane as a model of liquid fuel. The synthesized catalysts were characterized by XRD, FESEM, EDX, TEM, FTIR...

Sulfur compounds are major contaminants in diesel fuels and cause significant negative impacts on the environment, human health, petroleum product quality. Oxidative desulfurization (ODS) has gained attention due to relatively mild operating conditions. However, ODS requires improvements terms of productivity, reaction time, conversion. This study reports development a highly efficient, rapid p...

Sulfur compound content in fuels is one of the most undesirable pollutions regarding standard environmental regulations that demand to reduce sulfur concentration limit 5-10% fuels. Hence, kerosene’s oxidative desulfurization (ODS) as a model fuel (sulfur 1158ppm) with air an oxidant studied. The goal study use two different synthesized nanosilica-supported catalysts, CuO/SiO2 (CAT-1) and CuO/T...
