Catalyst and preparation method for said catalyst

Abstract

Abstract THIS INVENTION IS CONCERNED WITH CATALYSTS, PARTICULARLY THOSE USEFUL FOR HYDROCONVERSION, PREFERABLY HYDROCRACKING, A PROCESS FOR USING THE CATALYST, AND A METHOD FOR MAUNFACTURING THE CATALYST, WHICH COMPRISES: (A) FORMING IN AN AQUEOUS MEDIUM A GELATINOUS PRECIPITATE AND A FINELY DIVIDED CATALYTICALLY ACTIVE METAL, THE GELATINOUS PRECIPITATE COMPRISING AN INORGANIC OXIDE OR PRECURSOR THEREOF AND THE METAL BEING FORMED BY REDUCTION IN THE AQUEOUS MEDIUM OF A METAL COMPOUND DISSOLVED THEREIN; (B) INTIMATELY INTERMIXING THE GELATINOUS PRECIPITATE AND THE METAL WITHIN TWO HOURS OF FORMATION OF THE GELATINOUS PRECIPITATE, THEREBY FORMING A CATALYST PRECURSOR; (C) CONVERTING THE CATALYST PRECURSOR TO A CATALYST. THE CONVERSION INCLUDES AT LEAST A STEP OF HEATING THE CATALYST PRECURSOR AT 500-1800*F. FOR 1 TO 48 HOURS. THE PREFERRED CATALYST COMPRISES A NOBLE METAL, PREFERABLY PALLADIUM ON A SILICA-ALUMINA SUPPORT, PARTICULARLY USEFUL FOR HYDROCRACKING PROCESSES.
