Catalytic composition comprising a particulate mixture of ultrastable aluminosilicate - containing silica-alumina and cation-exchanged y-type molecular sieves and processes employing same
Abstract
Abstract THE CATALYTIC COMPOSITION COMPRISES A PHYSICAL PARTICULATE MIXTURE OF A COMPONENT (A) AND A COMPONENT (B). COMPONENT (A) COMPRISES AN AMORPHOUS SILICA-ALUMINA SUPPORT HAVING DISPERSED UNIDORMLY THROUGH THE MATRIX THEREOF AN ULTRASTABLE, LARGE-PORE CRYSTALLINE ALUMINOSILICATE MATERIAL AND HAVING IMPREGNATED THEREON A METAL OF GROUP VI-A, PREFERABLY MOLYBDENUM, AND A METAL OF GROUP VIII, PREFERABLY COBALT; COMPONENT (B) COMPRISES Y-TYPE MOLECULAR SIEVES WHICH HAVE BEEN CATIONEXCHANGED WITH A GROUP VIII METAL, PREFERABLY NICKEL. THE PROCESSES ARE HYDROCARBON-CONVERSION PROCESS EMPLOYING THIS CATALYTIC COMPOSITION, PARTICULARLY, A PROCESS FOR HYDROCARCKING NITROGEN-CONTAMINATED PETROLEUM HYDROCARBON FLUIDS.
