Treatment of hydrocarbons to produce a jet fuel and high octane gasoline

Claim 1

A PROCESS FOR THE PRODUCTION OF A JET FUEL OF HIGH LUMINOSITY NUMBER AND A MOTOR FUEL OF HIGH OCTANE NUMBER WHICH COMPRISES CONTACTING A HYDROCARBON OIL WITH A DENAPHTHENIZATION CATALYST UNDER DENAPHTHENIZATION CONDITIONS, EXTRACTING THE PRODUCT WITH FURFURAL TO PRODUCE AN EXTRACT PHASE AND A RAFFINATE PHASE, PASSING THE RAFFINATE PHASE SERIALLY THROUGH A PLURALITY OF REACTION ZONES AT A TEMPERATURE BETWEEN 770 AND 930*F. AND AN ELEVATED PRESSURE NOT GREATER THAN ABOUT 1000 P.S.I.G., THE LOWER THAN THE PRESSURE IN THE PRECEDING REACTION ZONE, REMOVING VAPOROUS MATERIAL FORMED IN EACH REACTION ZONE FROM THE REACTANT STREAM PRIOR TO PASSING THE REACTANT STREAM INTO THE NEXT DOWN STREAM REACTION ZONE WHEREBY THE HYDROCARBON REACTANT INTRODUCED INTO EACH REACTION ZONE IS SUBSTANTIALLY COMPLETELY IN THE LIQUID PHASE, SUBJECTING THE LIQUID PRODUCT STREAM TO FLASH DISTILLATION TO REMOVE MATERIAL BOILING THROUGH THE GAS OIL RANGE AS OVERHEAD FROM A RESIDUAL FRACTION, COMBINING SAID MATERIAL BOILING THROUGH THE GAS OIL RANGE WITH SAID VAPOROUS MATERIAL SAID VAPOROUS MATERIAL HAVING BEEN MAINTAINED APART FROM THE LIQUID REACTANT STREAM AFTER SEPARATION THEREFROM, SUBJECTING THE COMBINED STREAM TO FRACTIONAL DISTILLATION, REMOVING AS LIQUID BOTTOMS FROM SAID FRACTIONAL DISTILLATION MATERIAL BOILING ABOVE ABOUT 500*F., SEPARATING THE OVERHEAD FROM SAID FRACTIONAL DISTILLATION INTO A LIGHT LIQUID FRACTION BOILING UP TO ABOUT 300*F., CONTACTING THE LIGHT FRACTION WITH A REFORMING CATALYST UNDER REFORMING CONDITIONS WTH THE CONCOMITANT PRODUCTION OF HYDROGEN TO PRODUCE A MOTOR FUEL OF HIGH OCTANE NUMBER, CONTACTING THE HEAVY FRACTION WITH A HYDROGENATION CATALYST UNDER HYDROGENATION CONDITIONS TO REDUCE THE AROMATIC CONTENT THEREOF IN THE PRESENCE OF HYDROGEN PRODUCED BY THE REFORMING REACTION TO PRODUCE A JET FUEL OF HIGH LUMINOSITY NUMBER.
