Isotope exchange of H235S with the surface of sulphide catalysts Mo/SiO2 and (Ni-M)/SiO2 (M = Mo, W), prepared both by synthesis of surface metal complexes and by traditional impregnation, was studied. The rate of heteroexchange over the temperature range 150 to 300°C was shown to be almost the same on mono- and bimetallic sulphide catalysts obtained by the above procedure. The rate of thiophene hydrogenolysis increased with decreasing reactivity of surface sulphide groups towards the H235S heteroexchange.
