Method of making jet fuel and use thereof

Claim 1

THE METHOD OF MAKING A JET FUEL, WHICH COMPRISES EXTRACTING CYCLE OIL FROM A CATALYTIC CRACKING OPERATION WITH SULFUR DIOXIDE, EXTRACTING A RESULTING AROMATIC FRACTION EXTRACT WITH DIMETHYLSULFOXIDE, HYDRODESULFURIZING THE RESULTING AROMATIC FRACTION EXTRACT HAVING A SULFUR CONTENT OF 0.25 TO 2.5 WEIGHT PERCENT IN THE PRESENCE OF COBALT MOLYBDATE TO REDUCE SAID SULFUR CONTENT TO LESS THAN 0.05 WEIGHT PERCENT, AND HYDROGENATING THE RESULTING MATERIAL UNTIL IT IS 95 TO 100 WEIGHT PERCENT SATURATED.

Claim 2

THE METHOD OF MAKING A JET FUEL, WHICH COMPRISES EXTRACTING CYCLE OIL FROM A CATALYTIC CRACKING OPERATION WITH SULFUR DIOXIDE, EXTRACTING A RESULTING AROMATIC FRACTION EXTRACT WITH DIMETHYLSULFOXIDE, HYDRODESULFURIZING THE RESULTING AROMATIC FRACTION EXTRACT HAVING A SULFUR CONTENT OF 0.25 TO 2.5 WEIGHT PERCENT IN THE PRESENCE OF COBALT MOLYBDATE TO REDUCE SAID SULFUR CONTENT TO LESS THAN 0.05 WEIGHT PERCENT, AND HYDROGENATING THE RESULTING MATERIAL UNTIL IT IS 95 TO 100 WEIGHT PERCENT SATURATED.

Claim 3

THE METHOD OF OPERATING A JET ENGINE, WHICH COMPRISES MIXING FUEL AND AIR IN A COMBUSTION CHAMBER, CAUSING COMBUSTION OF SAID FUEL AND AIR, AND EJECTING THE COMBUSTION GASES THROUGH A NOZZLE TO PRODUCE A PROPULSIVE THRUST, SAUD FUEL BEING PREPARED BY EXTRACTING CYCLE OIL FROM A CATALYTIC CRACKING OPERATION WITH A SOLVENT SELECTED FROM THE GROUP CONSISTING OF SULFUR DIOXIDE AND FURFURAL, EXTRACTING THE RESULTING AROMATIC FRACTION EXTRACT WITH DIMETHYLSOLFOXIDE, THE RESULTING AROMATIC FRACTION EXTRACT BOILING WITHIN THE RANGE OF 450 TO 1000* F. AT ATMOSPHERIC PRESSURE AND HAVING A SULFUR CONTENT OF 0.25 TO 2.5 WEIGHT PERCENT, A NITROGEN CONTENT OF 0.03 TO 0.3 WEIGHT PERCENT, AND AN OXYGEN CONTENT OF 0.25 TO 2.5 WEIGHT PERCENT, HYDRODESULFURIZING THE LATTER AROMATIC FRACTION EXTRACT WITH HYDROGEN IN THE PRESENT, A NITROGEN CONTENT OF SULFURIZING CATALYST SELCTED FROM THE GROUP CONSISTING OF COBALT MOLYBDATE, MOLYBDENUM OXIDE, MOLYBDENUM SULFIDE, AND TUNGSTEN SULFIDE TO REDUCE THE SULFUR CONTENT TO LESS THAN 0.05 WEIGHT PERCENT AND THE OXYGEN CONTENT TO BELOW 0.05 WEIGHT PERCENT AND THE OXYGEN CONTENT TO BELOW 0.1 WEIGHT PERCENT, AND HYDROGENATING THE RESULTING MATERIAL IN THE PRESENCE OF A HYDROGENATION CATALYST TO PROVIDE A FUEL WHICH IS 95 TO 100 WEIGHT PERCENT SATURATED AND HAS A LUMINOMETER OF AT LEAST 30.

Claim 4

THE METHOD OF OPERATING A JET ENGINE, WHICH COMPRISES MIXING FUEL AND AIR IN A COMBUSTION CHAMBER, CAUSING COMBUSTION OF SAID FUEL AND AIR, AND EJECTING THE COMBUSTION GASES THROUGH A NOZZLE TO PRODUCE A PROPULSIVE THRUST, SAUD FUEL BEING PREPARED BY EXTRACTING CYCLE OIL FROM A CATALYTIC CRACKING OPERATION WITH A SOLVENT SELECTED FROM THE GROUP CONSISTING OF SULFUR DIOXIDE AND FURFURAL, EXTRACTING THE RESULTING AROMATIC FRACTION EXTRACT WITH DIMETHYLSOLFOXIDE, THE RESULTING AROMATIC FRACTION EXTRACT BOILING WITHIN THE RANGE OF 450 TO 1000* F. AT ATMOSPHERIC PRESSURE AND HAVING A SULFUR CONTENT OF 0.25 TO 2.5 WEIGHT PERCENT, A NITROGEN CONTENT OF 0.03 TO 0.3 WEIGHT PERCENT, AND AN OXYGEN CONTENT OF 0.25 TO 2.5 WEIGHT PERCENT, HYDRODESULFURIZING THE LATTER AROMATIC FRACTION EXTRACT WITH HYDROGEN IN THE PRESENT, A NITROGEN CONTENT OF SULFURIZING CATALYST SELCTED FROM THE GROUP CONSISTING OF COBALT MOLYBDATE, MOLYBDENUM OXIDE, MOLYBDENUM SULFIDE, AND TUNGSTEN SULFIDE TO REDUCE THE SULFUR CONTENT TO LESS THAN 0.05 WEIGHT PERCENT AND THE OXYGEN CONTENT TO BELOW 0.05 WEIGHT PERCENT AND THE OXYGEN CONTENT TO BELOW 0.1 WEIGHT PERCENT, AND HYDROGENATING THE RESULTING MATERIAL IN THE PRESENCE OF A HYDROGENATION CATALYST TO PROVIDE A FUEL WHICH IS 95 TO 100 WEIGHT PERCENT SATURATED AND HAS A LUMINOMETER OF AT LEAST 30.
