    Abstract: SOLID PHOSPHORIC ACID IS THE NAME WHICH HAS COME INTO USE FOR A CALCINED MIXTURE OF AN ACID OF PHOSPHOROUS AND A POROUS SILICEOUS MATERIAL. SOLID PHOSPHORIC ACID CATALYSTS HAVE FOR YEARS BEEN VIRTUALLY THE ONLY CATALYST EFFECTIVE IN MANY REACTIONS INVOLVING OLEFINS, PARTICULARLY THE POLYMERIZATION OF OLEFINS TO FORM HIGH OCTAN FUELS. THESE CATALYSTS ARE WIDELY USE DESPITE THEIR LACK OF STRENGTH AND POOR WEARING QUALITIES. HIGH STRENGTH SOLID PHOSPHORIC ACID CATALYSTS ARE PROVIDED HEREIN, THE UNIQUENESS OF THE CATALYST BEING ATTRIBUTABLE TO THE METHOD OR PREPARATION. P2O5 IS DRY BLENDED WITH THE SILICA MATERIAL TO FORM THE PRECURSOR. THE PRECURSOR IS THEN SUBJECTED TO A STEAM-AIR TREATMENT TO BRING ABOUT THE HYDRATION OF THE P2O5. THIS FORMS A SILICO-PHOSPHOROUS MATRIX. THID MATRIX IS PRESERVED BY NOT PHYSICALLY CHANGING THE CATALYST DURING ITS PREPARATION. THIS IS ACCOMPLISHED BY FORMING SPHERES OF THE CATALYST MATERIAL BY TUMBLING AND SPRAYING THE TUMING MASS WITH PHOSPHORIC ACID.

    Abstract: POROUS, ABRASION-RESISTANT BEAD-LIKE CATALYST SUPPORTS FOR REACTIONS IN FLUIDISED BEDS CONTAINING IN A MATRIX OF A SILICON DIOXIDE GELMIXED WITH 0.1 TO 3% BY WEIGHT OF MAGNESIUM OXIDE A SILICON DIOXIDE FILLER WITH A SPECIFIC SURFACE AREA OF 20 TO 200 M.2/G. ACCORDING TO BET IN QUANTITIES OF FROM 20 TO 60% BY WEIGHT AND AN ARGILLACEOUS MINERAL FROM THE GROUP COMPRISING KAOLINITE, MONTMORILLONITE AND ATTAPULGITE IN QUANTITIES OF FROM 5 TO 30% BY WEIGHT, BOTH QUANTITIES BEING RELATED TO THE DRY GRANULATED MATERIAL. THE CATALYST SUPPORTS ARE OBTAINED BY SUSPENDING THE SILICON DIOXIDE FILLER AND THE ARGILLACEOUS MINERAL IN THE AFORESAID QUANTITIES IN AN AQUEOS, STABLE SILICON DIOXIDE SOL WITH A SPECIFIC SURFACE AREA OF 150 TO 400 M.2/G. ACCORDING TO BET AND GELLING THE LIQUID SUSPENSION BY THE ADDITION OF HYDRATED FINALLY DIVIDED MAGNESIUM OXIDE IN QUANTITIES OF 0.1 TO 3% BY WEIGHT AND FEEDING THIS GELLABLE MIXTURE IN DROPLET FORM INTO A LIQUID WHICH IS IMMISCIBLE WITH WATER AND FINALLY SEPARATING THE SULPHATED GRANULATED MATERIAL FROM THE LIQUID AND DRIVING AND HARDENING THE BEAD-LIKE GRANULATED MATERIAL FOR AT LEAST 10 MINUTES AT A TEMPERATURE OF FROM 500 TO 1000*C.

    Abstract: A method of manufacturing an extruded catalyst composite of a Group VIII metal, a Group VIB metal and a refractory inorganic oxide-boron phosphate carrier material. A refractory inorganic oxide hydrogel is prepared and formed into a slurry with an aqueous solution of boric and phosphoric acids. The liquid level of the slurry is adjusted to form an extrudable mass comprising from about 15 to about 45 weight percent solids. The material is then extruded, impregnated with a metal of Group VIII and a metal of Group VIB, dried and calcined in an oxidizing atmosphere.
