Abstract
Abstract The mild hydrocracking (MHCK) is a very verstatile process where a wide catalytic functionality is needed. We will try to predict the application related to the activity for the main functions: hydrodesulfurization (HDS), hydrodenitrogenation (HDN), hydrocracking (HCK), hydrogenation (HYD) and hydrogenolysis (HYDL), using different criteria derived from their physicochemical properties. The physicochemical properties measured on the 11 analyzed catalysts were the bulk and surface chemical composition, physical properties (surface area and pore volume), the surface acidity, the crystalline phases and the surface parameters (metallic dispersion and sulfiding degree). Different correlations have been established among the surface properties and the catalytic activity.
