ABSTRACT:
There is provided a catalyst comprising yttrium containing zeolite Y. The zeolite Y is essentially free of rare earth ions. There is also provided a method for making this catalyst. There is further provided a process for using this catalyst for cracking gas oils. It has been discovered that when yttrium is incorporated into this zeolite Y, and when this catalyst is used to crack gas oils, these results improved gasoline selectivity and reduced dry gas make.
