A patent was just issued to Ultraclean Fuel with Gordon Gargano and Marc Halpern as the inventors that describes the large scale desulfurization of fossil fuel hydrocarbons to produce “ultralow sulfur diesel” (ULSD) and other ultralow sulfur hydrocarbon products that contain less than 10 ppm sulfur. These outstanding results require the use of a carefully selected phase-transfer catalyst, a phosphotungstate co-catalyst and hydrogen peroxide to oxidize covalently bound sulfur to sulfones. The sulfones are removed from the hydrocarbon stream to produce high quality desulfurized product. The patent reference is Gargano, G.; Halpern, M.; (Ultraclean Fuel Pty Ltd) US Patent 10,214,697, 26-Feb-2019.
Process equipment is described (Figures 4-6) that can process 1,500 barrels per day of high sulphur hydrocarbon feed (63,000 gallons) with the potential for 15,000 barrels per day (630,000 gallons).
This patent is a follow up to US Patent 9,441,169 by Gargano and Halpern.
The impressive breakthrough results are as follows:
“Transmix/Diesel feed containing a total sulphur level of 271 ppm was successfully desulphurised to a total sulphur level of 0 ppm according to ASTM D5623 standards and from 334 ppm to 2 ppm according to ASTM D5453 standards.”
“Transmix Diesel Hydrocarbon containing a total sulphur level of 407 ppm was successfully desulphurized to a total sulphur level of 9.2 ppm.”
“Refinery Diesel Hydrocarbon containing a total sulphur level of 3996 ppm was successfully desulphurized to a total sulphur level of 10 ppm.”
“Natural Gas Condensate containing a total sulphur level of 432 ppm was successfully desulphurized to a total sulphur level of 4.8 ppm.”
“Jet Fuel containing a total sulphur level of 1518 ppm was successfully desulphurized to a total sulphur level of 9 ppm.”
