Catalyst for elevated temperatures
Abstract
Abstract CATALYST CARRIER PARTICLES HAVING A LOW SURFACE AREA OPEN PORE STRUCTURE, AND LOW DENSITY AND CONSISTING OF CALCIUM SODIUM ALUMINO DISILICATE FOAM AND HAVING A NON-ZEOLITIC CRYSTALLINE STRUCTURE ARE PREPARED BY HEATING PRECURSOR PELLETS AT ABOUT 900-1150* C. FOR SEVERAL MINUTES. A IS PREPARED BY REFLUXING META KAOLIN IN 10% ZEOLITE A IS PREPARED BY REFLUXING META KAOLIN IN 10% SODIUM HYDROXIDE SOLUTION OR BY ANY OTHER ZEOLITE A SYNTHESIS. SUCH SODIUM ZEOLITE IS AT LEAST 50% ION-EXCHANGED TO THE CALCIUM FORM TO PROVIDE SAID PRECUSOR PELLETS. THE CERAMIC FOAM PARTICLES ARE IMPREGNATED WITH A LIQUID CONTAINING A METAL COMPONENT. THEREAFTER THE IMPREGNATED PARTICLE IS HEATED TO BOND THE CATALYTIC METAL TO THE FOAMED CERAMIC PARTICLE. SUCH PARTICLES COMPRISING CATALYTIC METAL COMPONENTS ON CERAMIC FOAM ARE CATALYSTS FOR REACTIONS CONDUCTED AT ELEVATED TEMPERATURES, COMPRISING HYDROLYSIS OF HYDROCARBONACEOUS MATERIAL, OXIDATION REACTIONS, AND HYDROGENATIVE AROMATIZATION OF HYDROCARBONACEOUS MATERIALS.
