Abstract
Abstract Improved hydrogenative conversion catalysts include one or more crystalline aluminosilicate zeolites, a hydrogenation component containing tungsten or molybdenum, and a Group IV metal stabilizing component containing titanium or zirconium. These compositions exhibit superior stability and hydrocracking, hydrofining and hydrogenation activity.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
48 words
THE CATALYTIC COMPOSITION CONTAINING A CRYSTALLINE ALUMINOSILICATE ZEOLITE, A GROUP VI METAL COMPONENT SELECTED FROM THE GROUP CONSISTING OF TUNGSTEN AND MOLYBDENUM METALS, OXIDES AND SULFIDES, AND A STABILIZING AMOUNT OF A STABILIZING COMPONENT COMPRISING A GROUP IV METAL SELECTED FROM THE GROUP CONSISTING OF TITANIUM AND ZIRCONIUM.
Claim 2
Dependent Claim
48 words
THE CATALYTIC COMPOSITION CONTAINING A CRYSTALLINE ALUMINOSILICATE ZEOLITE, A GROUP VI METAL COMPONENT SELECTED FROM THE GROUP CONSISTING OF TUNGSTEN AND MOLYBDENUM METALS, OXIDES AND SULFIDES, AND A STABILIZING AMOUNT OF A STABILIZING COMPONENT COMPRISING A GROUP IV METAL SELECTED FROM THE GROUP CONSISTING OF TITANIUM AND ZIRCONIUM.
Claim 3
Dependent Claim
65 words
The composition of claim 1 wherein said zeolite is selected from zeolites having crystal structures characteristic of zeolites A, L, T, Omega and faujasite, said composition contains at least about 5 weight-percent of said Group VI component determined as a corresponding oxide and at least about 0.1 equivalents of said Group IV metal per equivalent of said Group VI component based on the respective metals.
Claim 4
Dependent Claim
39 words
The composition of claim 1 containing at least about 5 weight-percent of said Group VI component as the oxide or sulfide and at least about 1 weight-percent of said stabilizing component determined as the corresponding Group IV metal oxide.
Claim 5
Dependent Claim
42 words
The composition of claim 3 wherein said zeolite comprises faujasite containing less than 2 weight-percent Na2O, and said composition comprises an amorphous refractory oxide and at least about 1 weight-percent of said stabilizing component determined as the corresponding Group IV metal oxide.
Claim 6
Dependent Claim
35 words
A composition as defined in claim 1 wherein said zeolite is a Y zeolite containing less than about 2 weight-percent Na2O and said catalytic composition also comprises a catalytic proportion of a nickel hydrogenating component.
