Controllable synthesis of obvious core–shell structured Y/Beta composite zeolite by a stepwise-induced method

Abstract

A stepwise-induced method with easy and simple preparations is proposed, which is used to successfully prepare the obvious core–shell structured Y/Beta composite zeolite using the pre-synthesized NaY-zeolite as a starting material. The composite zeolites with adjustable FAU/BEA features preliminarily present a good catalytic performance for cumene cracking, showing a strong potential application in petroleum processing.
