Hydrothermal method for manufacturing a novel catalytic material,catalysts containing said material,and processes using said catalysts

Abstract

Abstract (A) METHOD FOR MANUFACTURING A NOVEL CATALYTIC MATERIAL HAVING A SURFACE AREA ABOVE 200 SQUARE METERS PER GRAM, A BULK DENSITY BELOW 0.85 GRAMS PER CC. AND A MATERIAL COMPRISING A NOVEL SYNTHETIC LAYERED CRYSTALLINE CLAY-TYPE ALUMINOSILICATE MINERAL IN AN INTIMATE ADMIXTURE WITH AN AMORPHOUS COGEL COMPRISING SILICA AND ALUMINA, SAID MATERIAL BEING USEFUL AS A CATALYTIC CRACKING CATALYST AND AS A CRACKING COMPONENT OF A CATALYST CONTAINING AT LEAST ONE ADDITION COMPONENT, SAID METHOD COMPRISING SUBJECTING TO AUTOCLAVE CONDITIONS OF ELEVATED TEMPERATURE AND PRESSURE A HYDROGEL OR HYDROGEL SLURRY, SAID SLURRY COMPRISING WATER, A COMPONENT SELECTED FROM FLUORINE AND COMPOUNDS OF FLUORINE, AND AN AMORPHOUS COGEL COMPRISING OXIDES OR HYDROXIDES OF SILICON AND ALUMINUM, SAID SILICON AND ALUMINUM PREFERABLY BEING PRESENT IN SAID COGEL IN A SILICON-TO-ALUMINUM ATOMIC RATIO ABOVE 1.65 SAID ELEVATED TEMPERATURE BEING IN THE RANGE 340* TO 700*F., FOR A TIME NOT MORE THAN ANY OF THE TIMES RANGING LINEARLY FROM 36 HOURS AT 340*F. TO 6 HOURS AT 700* F., WHEREBY A SUBSTANTIAL AMOUNT OF SAID SYNTHETIC MINERAL IS FORMED, IN AN INTIMATE ADMIXTURE WITH A SUBSTANTIAL AMOUNT OF UNREACTED AMORPHOUS COGEL COMPRISING COMPOUNDS OF SILICON AND ALUMINUM, AND DRYING SAID INTIMATE ADMIXTURE TO PRODUCE SAID NOVEL CATALYTIC MATERIAL; (B) THE NOVEL CATALYTIC MATERIAL SO MANUFACTURED, COMPRISING SAID SYNTHETIC MINERAL IN SAID INTIMATE ADMIXTURE WITH UNREACTED AMORPHOUS COGEL, PREFERABLY CONTAINING AT LEAST 10 WEIGHT PERCENT OF SAID UNREACTED AMORPHOUS COGEL; (C) CATALYSTS COMPRISING SAID NOVEL CATALYTIC MATERIAL; AND (D) HYDROCARBON CONVERSION PROCESSES USING SAID CATALYST.
