Abstract

The present invention provides a process for oxidative desulphurization of liquid hydrocarbon fuels, such as diesel fuel, gasoline, jet fuel, fuel oils, coal liquids and similar petroleum products to ultra low sulphur hydrocarbon fuels with sulphur content less than 10 ppm. In this process, the sulfur compounds present in hydrocarbon fuel are first oxidised to more polar sulphones / sulphoxides and then removed by solvent extraction with NMP containing antisolvent followed by final polishing by passing through adsorption column.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to a process for the desulphurization of liquid hydrocarbon fuels. Particularly the invention relates to a process for oxidative desulphurization of liquid hydrocarbon fuels such as diesel fuel, gasoline, jet fuel, fuel oils, coal liquids and similar petroleum products to ultra low sulphur hydrocarbon fuels with sulfur content less than 10 ppm. More particularly, the present invention relates to oxidative desulphurization of liquid hydrocarbon fuels using carboxylic acid urea-H2O2 adduct, organosulphonic acid-H2O2 as oxidation system. BACKGROUND OF THE INVENTION

[0002] Hydrocarbon fuels such as diesel fuel, gasoline, jet fuel, fuel oils and coal liquids are presently being consumed in vast quantities and their consumption continues to grow at alarming rates, due to their high energy densities and convenient physical form. This high consumption inevitably has a major impact on global environment. Most notably transport hydro...
