Abstract: LOW POUR POINT LIGHT CYCLE GAS OIL FOR USE AS FURNACE OIL MAY BE OBTAINED WHEN CATALYTICALLY CRACKING A WAXY GAS OIL IF THE LIGHT GAS OIL FRACTION FROM THE CATALYTIC CRACKING UNIT IS LIMITED TO A BOILING RANGE OF ABOUT 430550*F. WHILE AN INTERMEDIATE GAS OIL FRACTION THEREFROM HAVING AN INITIAL BOILING POINT OF ABOUT 550 AND AN END POINT IN THE RANGE OF 650 TO 750*F. IS RECYCLED TO EXTINCTION BACK TO THE FEED TO THE CATALYTIC CRACKER. THE VIRGIN GAS OIL TO THE CATALYTIC CRACKER MAY HAVE AN IBP OF ABOUT 430 OR ABOUT 550*F. TO MAXIMIZE FURNACE OIL PRODUCTION WHEN THE IBP OF THE WAXY GAS OIL FEED TO THE CATALYTIC CRACKER IS ABOUT 550*F., THE LIGHT GAS OIL FRACTION FROM THE CATALYTIC CRACKER IS ADMIXED WITH A VIRGIN WAXY GAS OIL HAVING A BOILING RANGE OF ABOUT 430-550*F.
