Catalyst, especially for the treatment of industrial gases containing sulphur compounds, comprising a support and a supported phase made up in particular of a solid solution of average composition A4V2O9 in which A is a metallic element stabilising the vanadium in its valency 5. Process for the preparation of the said catalyst, consisting essentially in impregnating the support with a solution of a soluble salt of the metal element A and of a vanadyl salt. Process for the treatment of industrial gases containing sulphur compounds, especially of hydrogen sulphide and sulphur dioxide, with a view to removing the said sulphur compounds by the Claus reaction, in particular in the presence of oxygen, making use of the said catalyst.
