| abstract |
The present invention is in the field of heterogeneous catalysis. Particularly, the present invention relates to a process for preparing catalysts advantageously usable in the hydrotreatment processes, for example in hydrodesulphurization, hydrodenitrogenation, hydrodearomatization processes of hydrocarbons. More in particular, the present invention relates to a process for obtaining said catalysts, which comprise mixed oxides of Nickel, Aluminum, Molybdenum and Tungsten and optionally a transition metal Me selected from the group consisting of Zn, Mn, Cd, and a mixture thereof, an organic component C, and possibly an inorganic binder B. Said mixed oxides comprise an amorphous phase and a pseudo-crystalline phase isostructural to Wolframite. The present invention further relates to said hydrotreatment catalysts and a hydrotreatment process wherein said catalysts are used. |
