Provided is a Fluid Catalytic Cracking catalyst composition having increased propylene production with respect to other Fluid Catalytic Cracking catalysts (measured at constant conversion). The catalyst composition comprises a particulate which comprises (a) non-rare earth metal exchanged Y-zeolite in an amount in the range of about 5 to about 50 wt %, based upon the weight of the particulate; and (b) ZSM-5 zeolite in an amount in the range of about 2 to about 50 wt %, based upon the weight of the particulate.

Modified Y-zeolite/ZSM-5 catalyst for increased propylene production

A process for synthesizing a crystalline aluminosilicate zeolite having an MFI structure comprising crystallizing the zeolite from an alkaline aqueous reaction mixture that comprises SiO and Al O or their hydrated derivatives, and an amorphous aluminosilicate nucleating gel with an SiO /Al O ratio of from about 10 to less than 20. The reaction mixture does not contain an organic template.
