Abstract
The invention pertains to a zeolite catalyst, methods of making same, and its use in the catalytic cracking of naphtha for the production of lower molecular weight olefins and alkanes, while minimizing production less desirable products. A zeolite is modified by base leaching and by the addition of a metal cation, thereby lowering the Si/Alratio and improving the stability of the formed catalyst.
