Claim 1

A METHOD FOR PRODUCING SPECIALTY OILS WHICH COMPRISES DISTILLING A HEAVY ALKYLATE STREAM IN A FRACTINATING COLUMN TO OBTAIN A HEAVY ALKYLATE FRACTION BOILING IN THE RANGE FROM ABOUT 300* TO ABOUT 650*F., SUBJECTING SAID HEAVY ALKYLATE FRACTION TO HYDROFINING CONDITIONS COMPRISING A TEMPERATURE WITH THE RANGE FROM ABOUT 550* TO ABOUT 650*F., A PRESSURE WITHIN THE RANGE FROM ABOUT 150 TO ABOUT 500 P.S.I.G.,A SPACE VELOCITY WITHIN THE RANGE FROM ABOUT 2 TO ABOUT 10 V./V./HR., AND HYDROGEN IN AN AMOUNT WITHIN THE RANGE FROM ABOUT 100 TO ABOUT 1000 S.C.F./BBL. OF SAID HEAVY ALKYLATE FRACTION IN THE PRESENCE OF A SULFUR INSENSTIVE CATALYST, AMDIXING THE HYDROFINED FRACTION IN THE LIQUID PHASE AND AT A TEMPERATURE WITHIN THE RANGE FROM ABOUT 60*F. TO ABOUT 100*F. WITH A SOLUTION OF ALKALI METAL HYDROXIDE HAVING A BAUME GRAVITY FROM ABOUT 15* TO ABOUT 50*, SEPARATING THE HYDROFINED FRACTION FROM THE SOLUTION, AND THEN CONTACTING THE SEPARATED FRACTION IN THE LIQUID PHASE WITH AN ADSORBENT IN A STATIONARY BED, SAID ADSOBENT BEING SELECTED FROM THE GROUP CONSISTING OF ACTIVATED MAGNESIUM OXIDE, ACTIVATED CHARCOAL, MIXTURES OF ACTIVATED MAGNESIUM OXIDE AND ACTIVATED CHARCOAL, AND BAUXITE TO OBTAIN AN ODORLESS AND COLORLESS PRODUCT CONTAINING LESS THAN 10 P.P.M. OF SULFUR AND CONSISTING ESSENTIALLY OF 90 PERCENT TO 99 PERCENT SATURATED HYDROCARBONS WITH THE REMAINDER BEING OLEFINIC AND AROMATIC HYDROCARBONS.
