Abstract
Abstract HYDROCRACKING PROCESS FOR CONVERTING HIGH-BOILING HYDROCARBONS TO LOWER BOILING HYDROCARBONS, WHEREIN THE ESSENTIAL NOVEL FEATURE RESIDES IN UTILIZING, AT TEMPERATURES ABOVE ABOUT 600*F., A UNIQUE CLASS OF CATALYSTS COMPRISING (1) A GROUP VIII METAL-PROMOTED CRYSTALLINE ZEOLITE COMPONENT INTIMATELY COMPOSITED WITH (2) AN AMORPHOUS ALUMINA-SILICA COGEL COMPONENT CONTAINIG ABOUT 1-35 WEIGHT-PERCENT OF SILICA. AT TEMPERATURES ABOVE ABOUT 600* F., THESE CATALYSTS ARE FOUND TO DISPALY HIGHER ACTIVITES AND LOWER DEACTIVATION RATES THAN CERTAIN PRESUMABLY ANALOGOUS PRIOR ART CATALYSTS WHEREIN THE AMORPHOUS COMPONENT (2) CONTAINS HIGHER SILICA RATIOS, WHILE AT TEMPERATURES BELOW ABOUT 600*F.
