Abstract
A chemical-type hydrocracking catalyst contains the following components: a) a β zeolite, b) a layered MWW-type zeolite with a lamellar thickness of 2-12 nm, c) a metal functional component, d) a binder, and optionally e) a metal function regulating component. The catalyst can be used in hydrocracking reactions of feedstock oils rich in polycyclic aromatics for producing light aromatics and light alkanes.
Claims16
A hydrocracking catalyst, comprising the following components:
- a) a β zeolite, preferably a hydrogen-type β zeolite, b) a layered MWW-type zeolite, c) a metal functional component, and d) a binder, and optionally e) a metal function regulating component,
- wherein the layered MWW-type zeolite has a lamellar thickness of 2-12 nm.
Use of the layered MWW-type zeolite for conversion of polycyclic aromatics, wherein the lamellar thickness of the layered MWW-type zeolite is preferably in the range of 2-12 nm.
