Abstract: A CATALYST FOR OXIDATION OF SO2 TO SO3, WHICH CAN BE USED AS A FLUIDIZED BED CATALYST. AN ABRASIVE RESISTNT SUPPORT IS FORMED BY ADDING SILICA FILER AND A CLAY BINDER TO A SILICA SOL; ADDING HYDRATED MAGNESIUM OXIDE TO THE RESULTING MIXTURE, TO FORM A GELLABLE COMPOSITION; DISPRESING THE GELLABLE COMPOSITION IN A LIQUID TO FORM GEL SPHERES; CALCINING THE SPHERES; AND TREATING THEN WITH AN ACID TO REMOVE SOLUBLE COMPONENTS. AFTER THE ACID TREATMENT. THE SUPPORT IS IMPREGNATED WITH AN ALKALIMETAL VANDADATE SOLUTION AND CALCINED.

Abstract: The process for the production of bead-form silica-containing supported catalysts containing transition metals in ionic or elemental form which comprises mixing a filler comprising an alkaline earth metal silicate with an aqueous dispersion of an inorganic oxide hydrate, converting this mixture into a solid bead-form granulate, calcining the granulate, at a temperature of about 500* to 750* C., and then treating the product with a solution of a transition metal salt, whereby the alkaline earth metal ions present in the granulate are replaced at least in part by transition metal ions. The aqueous dispersion is preferably silica sol and the filler calcium silicate, possibly admixed with kaolin, montmorillonite or attapulgite. After ion exchange, the granulate may be treated with hydrogen to reduce the transition metal ion.

Abstract: A MIXTURE OF HYDRATED KAOLIN CLAY AND CALCINED KAOLIN CLAY (METAKAOLIN FORM) OR PARTIALLY REHYDRATED METAKAOLIN IS FORMED INTO PARTICLES SUCH AS EXTRUDED PELLETS. THE PARTICLES ARE CALCINED AT ABOUT 1350*F. TO CONVERT THE HYDRATED CLAY INTO METAKAOLIN. THE PARTICLES ARE THEN IMMERSED IN WATER AND HEATED UNDER SUPERATMOSPHERIC PRESSURE TO PROVIDE A CRACKING CATALYST.
