Desulfurization or desulphurisation is a chemical process for the removal of sulfur from a material. This involves either the removal of sulfur from a molecule or the removal of sulfur compounds from a mixture such as oil refinery streams.Desulfurization or desulphurisation is a chemical process for the removal of sulfur from a material. This involves either the removal of sulfur from a molecule ( e.g. A=S → A:) or the removal of sulfur compounds from a mixture such as oil refinery streams.

Among the desulfurization processes, the oxidative desulfurization (ODS) process is a promising method to achieve very low and near-zero sulfur content of the fuel. In this process, sulfur compounds are converted to the corresponding sulfone by a catalyst and in the presence of an oxidant. ...

The most important characteristics of crude oil that affect the market price are its sulfur content and gravity. Low sulfur content of crude oil is particularly preferred. Petroleum includes crude oil, natural gas, and heavy oil.API Gravity, Sulfur Content, and Desulfurization of Crude Oilاحصل على السعر
Abstract With the depletion of light and sweet crude oils, reliance and dependence on heavier crude oils will increase. However, refining of heavier crudes generates not only larger amounts of heavier products, but is also costly and involves problems of corrosion of equipment and poisoning of costly catalysts.

But with the control, the composition is more complex and the cost is higher.

The synthesized adsorbents were characterized by N2 sorption, X-ray diffraction (XRD), scanning electron ...Comparison of the Reactive Adsorption Desulfurization Performance of Ni ...احصل على السعر
Results showed that when roasting at 650 °C for 120 s, the desulfurization efficiency was up to 76.98%, while the residual sulfur in the roasted ore was found to be 0.07%. HU et al [24] roasted high-sulfur bauxite ore at 600 °C for 60 min, and the dissolution test was performed at 240 °C and roasted for 60 min.M Pourkhalil, AZ Moghaddam, A Rashidi, J Towfighi, Y Mortazavi.
