摘要： 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/Al2 ratio and improving the stability of the formed catalyst.

摘要： Methods for generating a purified catalyst are provided. The method includes performing a reaction in a reaction vessel to generate a liquid catalyst and reaction products, purging the reaction products using an inert gas to form a purged catalyst, freezing the purged catalyst in the reaction vessel, and applying a vacuum to the reaction vessel while the purged catalyst thaws, wherein the vacuum removes residual reaction products to form a purified catalyst. Systems for generating a purified catalyst and a purified catalyst are also provided.
