An FCC catalyst is made with a zeolite Beta which contains from about 0.1 to 15 wt % based on the weight of the zeolite Beta of gallium, zinc or mixtures thereof. The catalyst substantially increases the aromatic content of the gasoline compared to just using a catalyst of zeolite Beta. The catalyst can also be made with an inorganic oxide binder for the metal modified zeolite Beta and other catalytically active zeolite components.
