Process for the production of supersonic jet fuels

Claim 1

A PROCESS FOR PRODUCING A SUPERSONIC JET FUEL WHICH COMPRISES: TREATING A HYDROCARBON FEEDSTOCK CONSISTING ESSENTIALLY OF ALIPHATIC HYDROCARBONS IN THE RANGE OF C6-C9 WITH 50-100% H2SO4 IN AN H2SO4/FEEDSTOCK RATIO OF 0.5-10/1 BY WEIGHT AT A TEMPERATURE AND PRESSURE OF ABOUT 30-200*F. AND 10-200 P.S.I.G. RESPECTIVELY FOR A PERIOD OF ABOUT 0.1-60 MINUTES WHEREBY AT LEAST A PORTION OF SAID ALIPHATIC HYDROCARBONS IS POLYMERIZED AND ALKLYATED TO FORM A HYDROCARBON MIXTURE COMPRISING SATURATED AND UNSATURATED ALIPHATIC HYDROCARBONS IN THE C12-C30 RANGE; SUBJECTING AT LEAST A PORTION OF SAID HYDROCARBON MIXTURE TO HYDROGENATION TO CONVERT SAID UNSATURATED ALIPHATIC HYDROCARBONS TO SATURATED ALIPHATIC HYDROCARBONS; AND FRACTIONATING THE RESULTANT HYDROGENATED MIXTURE TO YIELD A FRACTION CONSISTING ESSENTIALLY OF SATURATED ALIPHATIC HYDROCARBONS HAVING A BOILING RANGE OF ABOUT 375-550*F., A HEATING VALUE ABOVE ABOUT 18,900 B.T.U./LB., A FREEZING POINT NO HIGHER THAN ABOUT -30*F., A LUMINOMETER NUMBER OF AT LEAST ABOUT 100, A VISCOSITY NO GREATER THAN ABOUT 15 CS. AT -30*F., A VAPOR PRESSURE NO HIGHER THAN ABOUT 50 P.S.I.A AT 500*F., A RESEARCH COKER FILTER PRESSURE DROP NO GREATER THAN ABOUT 5 IN. HG AND A RESEARCH COKER PREHEAT DEPOSIT RATING NO GREATER THAN ABOUT 2.
