Abstract:
A process for desulphurization of petroleum oil, comprising the step of diluting the feed oil with a suitable organic solvent prior to the desulphurization reaction, is disclosed. The organic solvent is selected from alkanes, alkenes, cyclic alkenes and alkynes, and particularly selected from n-hexane, cyclohexane, heptane, pentene, hexene, heptene, octene, toluene and xylene. The solvent concentration in the mixture of feed oil and solvent is in the range of 0.1-70%.

Claim (Index 1):
A process for desulphurization of petroleum oils, said process comprising the following steps:\n diluting petroleum oil with a hydrocarbon organic solvent selected from the group consisting of alkanes, alkenes, cyclic alkenes and alkynes, to obtain an oil-solvent mixture, wherein the organic solvent concentration in the oil-solvent mixture is in the range of 0.1-70%; transferring the oil-solvent mixture to a reactor vessel; adding solid sodium metal to the oil-solvent mixture in the reactor vessel, wherein the sodium concentration is between 0.1-20% of the petroleum oil concentration; reacting the oil-solvent mixture with sodium at a temperature in the range of 240-350\u00b0 C. and a pressure in the range of 0-500 psig for 15 minutes-4 hours under mixing to obtain a resultant mixture; cooling and settling the resultant mixture; and decanting the cooled mixture and filtering the decanted solution of desulfurized petroleum oil.
