  • Process for desulphurisation of liquid hydrocarbon fuels
    Publication number: 20070151901
    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.
