ABSTRACT:
The present invention relates to the novel catalytic composition having a high specific activity in reactions involving hydroprocessing of light and intermediate petroleum fractions, and preferably in hydrodesulphurization and hydrodenitrogenation reactions. The inventive catalyst contains at least one element of a non-noble metal from group VIII, at least one element from group VIB and, optionally, a group one element of the VA group, which are deposited on a novel catalytic support comprising of an inorganic metal oxide from group IVB, consisting of an (1D) one-dimensional nanostructured material having nanofibers and/or nanotube morphology with high specific surface area of between 10 and 500 m2/g.
