Catalyst

Abstract

The invention provides a catalyst composition useful in treating hydrocarbons contaminated with vanadium residues, the catalyst comprising a zeolite, a matrix and certain heavier alkaline earth metal oxides.

I claim: 
     
       1. A method of cracking vanadium containing hydrocarbon feedstocks wherein the feedstock is contacted with a catalyst composition comprising: (i) a crystalline zeolite,   (ii) a matrix material, and   (iii) a single phase crystalline mixed oxide selected from calcium and barium tin oxides, the strontium tin oxides Sr 2  SnO 4  and Sr 3  Sn 2  O 7 , strontium titanium oxides and .[.the barium titanium oxides BaTi 2  O 5 , BaTi 4  O 9 , BaTi 5  O 11 , Ba 2  TiO 4 , Ba 2  Ti 5  O 12 , Ba 2  Ti 9  O 20 , Ba 4  Ti 13  O 30 , and Ba 6  Ti 17  O 40 , and.]. mixtures thereof.
