<p>A catalyst composition and process for the utilization of said catalyst. The catalyst is a zeolitic crystalline aluminosilicate dispersed in an amorphous silica-alumina matrix. The catalyst is manufactured by adding a crystalline aluminosilicate to an alumina-silica gel containing an organic polymer and spray drying the gel at a temperature sufficient to decompose the polymer. The catalyst is particularly effective in the catalytic cracking of hydrocarbon charge stocks.</p> |
