Abstract
This invention reveals a method for synthesizing a hydrotreating catalyst wherein the support is prepared by mixing of peptized alumina with an amorphous silica or crystalline aluminum silicate as one component of the catalyst. The catalyst comprises a group VI metal and/or a group VIII metal of the periodic table. The catalyst exhibits improved hydrocracking, hydrodesulfurization and hydrodemetallization activities and has a relatively stable life with time on stream. Thus, the invention concerns a method for developing a catalyst for hydroprocessing of heavy hydrocarbon feedstocks which is characterized by two steps: the first step consists of the optimization of a catalyst formulation with respect to the textural properties, number of acid sites, active metal incorporation. The second step consists of the evaluation with real feedstock and catalyst stability with time-on-stream.
