This patent describes a process for catalytic cracking of hydrocarbon feedstocks. It comprises contacting the hydrocarbon feedstock under conditions effective to crack the feedstock with a catalyst. The catalyst is prepared by a process comprising the following step: contacting a fluid mixture of a large pore zeolite having a SiO/sub 2/Al/sub 2/O/sub 3/ ratio of about 3.5 to less than about 20 and an inorganic oxide matrix, with a fluoro salt of the formula A/sub (n-m)/(MF/sub n/)/sub z/. Wherein A is an organic or inorganic ionic moiety; (MF/sub n/)/sub z/ is a fluoroanion moiety comprising the element M; M is an element selected from the group of elements for Groups VB, VIB, VII, IIIA, IVA and VA of the Periodic Table of Elements; n is the coordination number of M; m is the valence of M and z is the valence or charge associated with A, at an effective pH value greater than about 3, at effective conditions of temperature and time to produce a catalyst product, whereby the cracking activity of the zeolite is enhanced.
