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.
Claims18
A hydrocracking catalyst for a feedstock oil rich in polycyclic aromatics, comprising:
- a) a β zeolite, b) a layered MWW-type zeolite, c) a metal functional component, d) a binder, and e) a metal function regulating component,
- wherein the layered MWW-type zeolite has a lamellar thickness of 2-12 nm,
- wherein the metal functional component is in a non-sulfurized state and is selected from platinum, palladium, a combination of platinum and palladium, a combination of at least one of a Group VIII metal, a Group IIB metal, and a Group VIB metal oxide, and
- wherein the metal function regulating component is selected from tin, bismuth, and combination thereof.
