Abstract
A method and catalyst mixture for hydroprocessing a hydrocarbon feed stream through a moving catalyst bed having a catalyst mixture and contained within a single onstream reactor vessel. The reactor vessel contains the catalyst mixture which includes two or more different and distinct catalyst for any hydroprocessing application. The different and distinct catalyst have different catalyst density and are designed for a different function, such as HDM and HDN. The different and distinct catalysts can also have different average residence times if their densities and physical properties are properly selected.
