A REFORMING PROCESS WHICH COMPRISES CONTACTING A NAPHTHA FRACTION UNDER SUITABLE REFORMING CONDITIONS WITH A CATALYST COMPRISING MOLYBDENUM OXIDE ON ALUMINA, WHICH ALUMINA IS PREPARED BY PRECIPITATING ALUMINA GEL BY THE REACTION OF AN ALKALINE REAGENT WITH AN ALIMINUM SALT, DRYING SAID GEL AT A TEMPERATURE BETWEEN ABOUT 150* F. AND ABOUT 400* F. AND THEN RECONSTITUTING THE GEL BY RESLURRYING IN AN AQUEOUS MEDIUM, THEN TREATING THE RECONSTITUTED ALUMINA GEL WITH AN ALKALINE REAGENT FOR A PERIOD OF TIME SUFFICIENT TO CONVERT THE SAME TO A GELATINOUS PRECIPITATE AND SUBJECTING THE GELATINOUS PRECIPITATE TO A CALCINATION TREATMENT TO CONVERT THE SAME TO DESIRED SUPPORT MATERIAL.
