THE METHOD OF DECOLORIZING A PETROLEUM WAX WITHOUT SUBSTANTIALLY EFFECTING THE MELTING POINT, SULFUR CONTENT OR PENETRATION CHARACTERISTICS OF SAID WAX WHICH CONSISTS IN SUBJECTING SAID PETROLEUM WAX TO HYDROGENATION IN THE PRESENCE OF ABOUT 2500 S.C.F. OF HYDROGEN PER BARRLE OF SAID WAX, AT A TEMPERATURE OF ABOUT 550*F. AND A PRESSURE OF ABOUT 100 P.S.I.G., USING A SPACE VELOCITY OF ABOUT 1.3 IN THE PRESENCE OF A CATALYST CONSISTING OF ABOUT 9.0 PERCENT BY WEIGHT OF MOLYBDENUM OXIDE ON AN ALUMINA CARRIER, SAID CATALYST BEING PREPARED BY PRECIPITATING ALUMINUM HYDROXIDE FROM ALUMINUM SULFATE, DISPERSING THE PRECIPITATED ALUMINUM HYDROXIDE IN A SOLUTION OF AMMONIUM MOLYABDENUM TRIOXIDE BY HEATING THE REMOLYBDATE TO MOLYBDENUM TRIOXIDE BY HEATING THE RESULTANT IMPREGNATED MASS TO A TEMPERATURE OF ABOUT 850* TO 950*F., AND RECOVERING FROM SAID HYDROGENATION REACTION A PRODUCT HAVING IMPROVED COLOR AND SUBSTANTIALLY THE ORIGINAL MELTING POINT, SULFUR CONTENT AND PENETRATION CHARACTERISTICS.
