Abstract
NEW TECHNIQUES OF BENTONITE ACTIVATION AND THEIR EFFICIENCY IN USED MOTOR OIL (UMO) REGENERATION HAVE BEEB ASSESSED. FOUR METHODS OF RECYCLING USED LUBRICATING OIL (HAVING RUN ABOUT 15 000-20 000 KM) HAVE BEEN EMPLOYED, SUCH AS HEAT/BENTONITE TREATMENT, Na2CO3 /BENTONITE COMBINED WITH MICROWAVE TREATMENT, ACID/BENTONITE COMBINED WITH MICROWAVE TREATMENT, AND NaOH/BENTONITE COMBINED WITH MICROWAVE TREATMENT. VARIOUS TESTS HAVE BEEN CARRIED OUT ON THE RECYCLED USED LUBRICATING OIL, INCLUDING THOSE FOR DENSITY, KINEMATIC VISCOSITY, VISCOSITY INDEX. POUR POINT, COLOR, AND SULFUR CONTENT. THE RESULTS SHOWED THAT ACID - ACTIVATED BENTONITE FOLLOWED BY MICROWAVE TREATMENT WAS MORE EFFICIENT FOR UMO REGENERATION COMPARED TO THE OTHER METHODS.
