Hydrocracking Composite Catalysts Based on Zeolite and Amorphous Silica-Alumina

A method of preparing a hydrocracking catalyst, the method comprising:

• forming an ordered amorphous silica-alumina (OASA) comprising mesopores by at least partially hydrolyzing a first zeolite;
• mixing the OASA with a second zeolite to form a catalyst precursor mixture;
• adding a binder and a support material to the catalyst precursor mixture to form a catalyst paste;
• extruding the catalyst paste to form a catalyst extrudate;
• and
• calcining the catalyst extrudate to form a composite catalyst comprising,
• the OASA,
• the second zeolite,
• a first metal component,
• a second metal component,
• the binder, and
• the support material.

An extrudate catalyst composition comprising:

• 30-50 wt. % an ordered amorphous silica-alumina (OASA) having mesopores;
• 15-25 wt. % a binder;
• 14-20 wt. % a first metal component;
• 5-15 wt. % a support material;
• 4-8 wt. % a second metal component;
• and
• 2-15 wt. % a zeolite component.
