Process for the production of traction fluid
Abstract
Abstract A LIGHT LUBE SUITABLE FOR USE AS A TRACTION FLUID IS PREPARED FROM A GAS OIL BY HYDROCRACKING. THE PROCESS INVOLVES TREATING THE GAS OIL OVER A CATALYST SUCH AS SUPPORTED NICKEL-MOLYBDENUM, AT FROM 680 TO 780* F. AND 800 TO 2000 P.S.I.G. IN THE PRESENCE OF HYDROGEN TO CONVERT THE SULFUR PRESENT TO HYDROGEN SULFIDE AND THE NITROGEN PRESENT TO AMMONIA. THE GAS OIL IS THEN HYDROCRACKED USING MAGNESIUM ZEOLITE Y CONTAINING 0.2 TO 2.0 WEIGHT PERCENT OF A NOBLE METAL AT FROM 680 TO 780* F. AND FROM 800 TO 2000 P.S.I.G. THE RESULTING HYDROCRACKATE IS WATER WASHED TO REMOVE THE HYDROGEN SULFIDE AND AMMONIA. THE PORTION OF THE HYDROCRACKING BOILING BELOW 650-750* F. IS RECYCLED TO THE HYDROCRACKER. THE HIGHER BOILING PORTION OF THE HYDROCRACKATE IS DEWAXED TO PRODUCE THE HYDROCRACKED LUBE PRODUCT, USEFUL AS A TRACTION FLUID.
