Hydrocracking process to produce gasoline and turbine fuels

Claim 1

A PROCESS FOR CONVERTING A HIGH BOILING MINERAL OIL INTO GASOLINE AND AVIATION TURBINE FUEL WHICH COMPRISES CONTACTING SAID MINERAL OIL AND HYDROGEN WITH A HYDROFINING CATALYST AT HYDROFINING CONDITIONS TO REMOVE ORGANIC NITROGEN COMPOUNDS FROM THE OIL, CONTACTING THE HYDROFINED OIL AND HYDROGEN IN A HYDROCRACKING ZONE WITH A HYDROCRACKING CATALYST COMPRISING A HYDROGENATING-DEHYDROGENATING COMPONENT IN ASSOCIATION WITH AN ACTIVE ACID-ACTING CRACKING CATALYST AT HYDROCRACKING CONDITIONS, PARTIALLY COOLING EFFUENT FROM THE HYDROCRACKING ZONE, SEPARATING THE PARTIALLY COOLED EFFLUENT INTO A GASEOUS PHASE CONTAINING HYDROCARBONS IN THE GASOLINE BOILING RANGE AND A LIQUID PHASE CONTAINING HYDROCARBONS IN THE AVIATION TURBINE FUEL BOILING RANGE, CONTACTING THE LIQUID PHASE AND HYDROGEN WITH AN ACTIVE HYDROGENATION CATALYST ON A SUBSTANTIALLY INERT POROUS SUPPORT AT CONDITIONS INCLUDING A TEMPERATURE IN THE RANGE FROM ABOUT 250* TO 600*F. TO HYDROGENATE AROMATIC HYDROCARBONS TO NAPHTHENES, COOLING THE GASEOUS PHASE AND RECOVERING A NORMALLY LIQUID HYDROCARBON OIL, RECOVERING A NORMALLY LIQUID HYDROCARBON OIL AND THE HYDROGENATED LIQUID A HEAVY GASOLINE FRACTION AND AN AVIATION TURBINE FUEL FRACTION HAVING AN AROMATIC CONTENT LESS THAN 20% BY VOLUME, AND CATALYTICALLY REFORMING THE HEAVY GASOLINE FRACTION.
