Abstract

The invention concerns a catalyst containing at least one amorphous oxide matrix, at least one carbide and phosphorous deposited on said catalyst or contained in the matrix, in which the carbide contain at least one group VIB element and, optionally, at least one element from group VIII of the periodic table. The invention also concerns the use of the catalyst for hydrodesulphurisation and hydrogenation of aromatic compounds in gas oils with a low sulphur content.
