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...

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...

Catalyzed sulfonation of methane to methanesulfonic acid

Direct sulfonation of methane with SO3 to methanesulfonic acid (MSA) and methylbisulfate was investigated in sulfuric acid using Hg(I), Hg(II), and Rh(III)-salts as catalysts. O2 was found to be an important component for the regeneration of the catalyst. The effects of O2 pressure, temperature, SO3 concentration, methane pressure, and catalyst concentration were examined on the rates of SO3 co...

Deep desulfurization of diesel by adsorption over Ni/ZSM-5

Introduction Environmental restriction regarding the quality of transportation fuels and the emissions from them are the most important issues. Because of more stringent regulations and fuel specifications regarding development of better method for deep-desulfurization of fuels are important. There has been recent interest in developing adsorbents for selective desulfurisation by adsorption. Me...
