Reductive Desulfurization of Dibenzyldisulfide

Desulfurization of Coal

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...

Reductive desulfurization of allylic thiols by HS-/H2S in water gives clue to chemical reactions widespread in natural environments.

The reduction of allylic thiols to alkenes by hydrogen sulfide in aqueous solutions, a novel reaction that may explain reduction processes widely occurring in natural environments, has been discovered. Its mechanism has been studied and suggested to follow an S(RN)1-like pathway involving radical intermediates undergoing 1,4 hydrogen shifts. [reaction: see text]

Desulfurization of Gas Oil by Modified Clinoptilolite

The objective of this research is to find an economically attractive alternative method for hydrodesulfurization of petroleum fractions and to select a suitable adsorbent for this process.Deep desulfurization of transportation fuels (gasoline, diesel, and jet fuels) is being mandated by governments and is also needed for future fuel cell applications. However, it is extremely difficult and ...

Natural Gas Odorants Desulfurization

This study investigates the use of activated carbon for the odorant removal from natural gas to be used for synthesis gas production for fuel cells. The odorants used in this study were dimethyl sulfide, tetrahydrothiophene, methyl mercaptan, and t-butyl mercaptan. It was concluded that only physical adsorption is contributing towards removal of sulfur species at lower temperatures, whereas the...
