Claim 18:
19. Calcined catalyst particles comprising a composite of
post-framework modified ultra-stable Y-type (USY) zeolite in which a portion of aluminum atoms constituting a zeolite framework thereof is substituted with zirconium atoms and/or titanium atoms and/or hafnium atoms, wherein the post-framework modified USY zeolite is characterized by outer surfaces and pores which define inner surfaces, and wherein said outer surfaces and/or pore inner surfaces of the post-framework modified USY zeolite are metal-loaded with a first portion of a total active metal component content of one or more active metal components; and
inorganic oxide binder material,
wherein the composite is characterized by outer surfaces and pores which define inner surfaces, and wherein said outer surfaces and/or pore inner surfaces of the composite are metal-loaded with a second portion of the total active metal component content of one or more active metal components, as metal-loaded composite;
wherein said metal-loaded composite is formed into extrudates and thermally treated as the calcined catalyst particles.
