Steaming Drived Chemical Interactions of ZnClx with Y Zeolite Framework, Its Regulation to Dealumination/Silicon-Healing as well as Enhanced Availability of Brønsted Acidity

Abstract

In fluid catalytic cracking (FCC), Bronsted acid plays a very important role. Herein, a zinc-modified ultrastable Y (USY) zeolite containing higher Bronsted acidity was prepared by synergistic trea...
