A METHOD FOR PRODUCINGG A JET COMBUSTION FUEL AND AROMATIC HYDROCARBONS WHICH COMPRISES: CONTACTING A HYDROCARBON CHARGE STOCK UNDER HYDROCRACKING CONDITIONS IN THE PRESENCE OF A HYDROCRACKING CATALYST AND HYDROGEN IN AMOUNTS, EXPRESSED IN MOLAR RATIO OF HYDROGEN TO HYDROCARBON CHARGE, WITHIN THE RANGE ABOUT 2 TO ABOUT 80, TO CONVERT AT LEAST A PORTION OF THE HYDROCARBON CHARGE INTO JET FUEL BOILING RANGE MATERIAL WITH AN INITIAL BOILING POINT OF AT LEAST 160*F. AND AN END BOILING POINT WITHIN THE RANGE ABOUT 450*F. TO ABOUT 550*F., SEPARATING SAID JET FUEL BOILING RANGE MATERIAL INTO A CRACKET NAPHTHA FRACTION AND A HYDROCRACKED FRACTION HAVING AN INITIAL BOILING POINT WITHIN THE RANGE ABOUT 300 TO ABOUT 400*F. AND AN END BOILING POINT WITHIN THE RANGE ABOUT 450*F. TO ABOUT 550*F., REFORMING SAID CRACKED NAPHTHA FRACTION IN THE PRESENCE OF A REFORMING CATALYST AND UNDER REFORMING CONDITIONS TO PRODUCE A REFORMATE, REMOVING AROMATIC HYDROCARBONS FROM SAID REFORMATE TO PRODUCE AN AROMATIC FRACTION AND A NON-AROMATIC FRACTION, COMBINING SAID NON-AROMATIC FRACTION WITH SAID HYDROCRACKED FRACTION HAVING AN INITIAL BOILING POINT WITHIN THE RANGE ABOUT 300*F. TO ABOUT 400*F. AND AN END BOILING POINT WITHIN THE RANGE ABOUT 450*F. TO ABOUT 550*F. TO PRODUCE THEREBY A FINISHED JET FUEL, AND RECOVERING AROMATIC HYDROCARBONS FROM SAID AROMATIC FRACTION.
