Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
176 words
A METHOD OF PREPARING A SOLID POROUS HYDROCARACKING CATALYST WHICH COMPRISES MIXING AN AQUEOUS SOLUTION OF AN ALKALI METAL SILICATE WITH AN AQUEOUS SOLUTION OF A ZIRCONIUM SALT AND AN ALUMINUM SALT TO YIELD A HYDROSOL HAVING A PH OF FROM 7 TO 10 CAPABLE OF SETTING TO A HYDROGEL CONTAINING FROM 5 TO 15 PERCENT ZRO2, FROM 5 TO 10 PERCENT AL2O3, AND FROM 75 TO 90 PERCENT SIO2 BASED ON COGELLED OXIDE CONTENT, PERMITTING SAID HYDROSOL TO SET TO A HYDROGEL, ACTIVATING SAID HYDROGEL BY TREATMENT FOR FROM 1 TO 24 HOURS AT A TEMPERATURE OF FROM 125 TO 200*F. WITH AN AQUEOUS SOLUTION OF A COMPOUND SELECTED FROM THE GROUP CONSISTING OF A MINERAL ACID, AN ALUMINUM SALT, AND MIXTURES THEREOF, SAID SOLUTION HAVING A PH OF FROM 0 TO 7, WASHING SAID HYDROGEL FREE OF WATER-SOLUBLE MATERIAL, DRYING, CALCINING, AND COMBINING THE RESULTING SILICA-ZIRCONIA-ALUMINA GEL WITH A HYDROGENATION COMPONENT SELECTED FROM THE GROUP CONSISTING OF OXIDES OF METALS, SULFIDES OF METALS AND METALS OF GROUPS VI AND VIII OF THE PERIODIC TABLE.
