Abstract
A process is disclosed for preparing a noble metal-containing zeolite catalyst of high noble metal dispersion. The process of crystallizing a zeolite from a forming mixture which contains an organic template, treating the zeolite by calcining or chemical oxidation to remove the template from the zeolite, mulling the zeolite with an inorganic oxide binder and a noble metal-containing solution, and thereafter extruding the blended mixture.
Claims42
A process for preparing a noble metal-containing zeolite catalyst which comprises crystallizing a zeolite from a forming mixture which contains an organic template, treating the as-crystallized zeolite to remove greater than about 75% by weight of said template from the zeolite, blending said zeolite with an inorganic oxide binder and a noble metal-containing solution, and extruding the blended mixture.
A noble metal-containing zeolite catalyst comprising a crystalline zeolite, an inorganic oxide binder and a noble metal, wherein said catalyst has a noble metal dispersion greater than about 0.50 and noble metal crystallites of less than about 30A.
A process for preparing a noble metal-containing zeolite catalyst, which process comprises crystallizing zeolite beta from a forming mixture which contains an organic template, treating said zeolite to remove said template from the zeolite, blending said zeolite with an alumina binder and thereafter adding a solution containing an anionic species of a noble metal and extruding the resulting mixture.
