Abstract
Methods of making hydrotreating catalysts are provided having one or more phosphorus components carried on a composite support of a titanium-loaded binder component and post-framework modified ultra-stable Y-type zeolite. The support comprises the titanium-loaded binder component and a post-framework modified ultra-stable Y-type (USY) zeolite. The active components including the phosphorous active component and one or more hydrocracking metals active components loaded on the support.
Claims20
A method for making hydrocracking catalyst particles comprising:
- providing post-framework modified ultra-stable Y-type (USY) zeolite component 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;
- providing a titania-containing binder component;
- mixing and kneading the post-framework modified USY zeolite component with the titania-containing binder component to form a composite;
- forming the composite into extrudates;
- thermally treating the extrudates;
- recovering intermediate calcined catalyst particles that are characterized by outer surfaces and pores which define inner surfaces;
- and
- loading active components comprising a phosphorus component and one or more hydrocracking metal active components to form the hydrocracking catalyst particles.
