Desulfurization of gasoline.

Desulfurization of gasoline.

Although gasoline blending streams exhibit widely varying sulfur concentrations, significant quantities of low-sulfur motor gasoline cannot be manufactured by reallocation of existing components without substantial sacrifices in the useful properties of the remaining fuels having normal sulfur levels. To meet the anticipated demand for low-sulfur unleaded gasoline which may be required for cata...

Simulation Study of Ionic Liquid Utilization for Desulfurization of Model Gasoline

With the increased amount of focus is being put towards reducing the emissions results from fossil fuel usually composed of hydrocarbons and impurities. The study aim at utilizing the ability of 1-octyl-3-methylimidazolium tetrafluoroborate [OMIM][BF4]. Ionic liquid as the suitable solvent for the extraction of the thiophene and its derivatives from the model gasoline. The proces...

Adsorptive Desulfurization of Model Gasoline by Using Different Zn Sources Exchanged NaY Zeolites.

A series of Zn-modified NaY zeolites were prepared by the liquid-phase ion-exchange method with different Zn sources, including Zn(NO₃)₂, Zn(Ac)₂ and ZnSO₄. The samples were tested as adsorbents for removing an organic sulfur compound from a model gasoline fuel containing 1000 ppmw sulfur. Zn(Ac)₂-Y exhibited the best performance for the desulfurization of gasoline at ambient conditions. Combin...

Synthesis and characterization of TBA-PV2Mo10@PVA as an efficient and reusable heterogeneous catalyst for oxidative desulfurization of gasoline

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...
