Hydroprocessing catalysts are an essential part of any refinery involved in the treatment/conversion of most petroleum fractions ranging from naphtha to residue (FIG. 1). Hydrotreating catalysts help refiners meet fuel regulations and enhance the performance of downstream catalysts and processes [e.g., naphtha reforming or fluid catalytic cracking (FCC)] by removing sulfur, nitrogen and metals from their feedstocks as well as improving product properties by hydrogen addition. Moreover, hydrocracking catalysts further improve refiners’ profits by converting low-value streams [e.g., vacuum gasoil (VGO)] into high-value fuels and chemical feedstocks. Therefore, selecting hydroprocessing catalys
