Реферат:
Sulphide catalysts (Ni,W)/SiO2 and (Ni,Mo)/SiO2 have been prepared using surface allyl complexes of tungsten, molybdenum and nickel as precursors for sulphide particles. When Ni was added to sulphided Mo/SiO2 and W/SiO2 catalysts 10-90 times increase of activity in thiophen hydrogenolysis was observe. The most active catalysts were prepared via anchoring of organometallic compounds of one element on dispersed sulphide particles of another element. Activity referred to the total amount of two metals has the maximum value at λ = Ni/[Ni+W(Mo)] = 0.2-0.4. Activity referred to one g atom of Ni increased with decreasing Ni content and reached the maximum value at a λ ≦0.2. Mixed catalysts prepared by conventional impregnation method are found to be some times less active than samples prepared from organometallic precursors. The data obtained are in favour of providing intimate mixing of two sulphides for preparation of active catalysts.
