A PROCESS OF MAKING A JET FUEL WHICH COMPRISES: FRACTIONATING FRACTIONATING A PARAFFINIC CRUDE OIL STREAM TO OBTAIN A CHARGE STREAM BOILING WITHIN THE RANGE OF 355*F. TO 510*F.; CONTACTING SAID CHARGE STREAM WITH HYDROGEN AND A DHYDODESULFURIZATION CATALYST UNDER HYDRODESULFURIZATION CONDITIONS TO OBTAIN A DESULFURIZED STREAM CONTAINING LESS THAN 0.01% SULFUR BY WEIGHT; CONTACTING SAID DESULFURIZED STREAM WITH HYDROGEN AND A REFORMING CATALYST AT A TEMPERATURE FROM 825*F. TO 900*F., A PRESSURE FROM 150 P.S.I.G. TO 450 P.S.I.G., AND A SPACE VELOCITY FROM 0.2 TO 2.0 V./V./HR., WHEREBY NAPHTHENE AROMATIZATION AND NORMAL PARAFFIN ISOMERIZATION ARE MAXIMIZED IN OBTAINING A REFORMED STREAM; EXTRACTING SUBSTANTIALLY ALL OF THE AROMATIC HYDROCARBONS FROM SAID REFORMED STREAM BY CONTACT WITH A SOLVENT FOR AROMATIC HYDROCARBONS TO OBTAIN A RAFFINATE CONTAINING LESS THAN 3% AROMATIC HYDROCARBONS; HYDROFINING SAID RAFFINATE BY CONTACT WITH HYDROGEN AND A HYDROFINING CATALYST UNDER HYDROFINING CONDITIONS TO OBTAIN A HYDROFINED PRODUCT; AND CONTACTING SAID HYDROFINED PRODUCT WITH AN ADSORBENT FOR POLAR COMPOUNDS TO OBTAIN A THEREMALLY STABLE JET FUEL;
