ABSTRACT:
The present invention is concerned with upgrading residual oils to gasoline product with a coke selective hydrogen stable faujasite crystalline zeolite catalyst comprising at least 40 weight percent of alumina and rare earth metals in an acidic matrix and effecting regeneration thereof in an oxygen lean atmosphere under CO combustion conditions. A compound of antimony is added to passivate metal contaminants. The regeneration of the catalyst is effected to retain up to 0.25 weight percent carbon and heat balance of the operation is limited as a function of metal promoted CO burn within a dense fluid bed of catalyst being regenerated.
