Abstract
A method of preparing a hydroprocessing catalyst that may have a high metals loading and has a particularly high activity for hydrodenitrogenation. The method uses several metal impregnations in combination with different intermediate treatment steps so as to provide a catalyst composition that includes a mix of different types of catalytically active sites. The method of the invention allows for the optimization and control of the relative ratio of the different types of active catalyst sites on the catalyst composition in order to give certain desired results and improved catalytic performance. The catalyst composition comprises a one or more active metals or active metal precursors that are incorporated onto a support material.
