Abstract
Unpromoted and nickel-promoted catalysts were synthesized on the basis of the Anderson heteropoly compounds (NH4)6 − x [X x(OH)6Mo6O18] · nH2O, where heteroatom X is Cr(III), Mn(II), Fe(II), Ni(II), Co(II), Cu(II), Zn(II), or Ga(III), and their activity in the thiophene hydrogenolysis reaction and hydrofining of diesel fraction was examined. It was shown that the most active hydrotreating catalysts under the test conditions in a flow unit were the samples with X = Ni, Mn, or Zn. The catalysts synthesized from the Keggin heteropoly compounds H4[SiMo12O40] · 17H2O, H3[PMo12O40] · 19H2O, H3[PVMo11O40] · nH2O, and (NH4) x [V(MoO3)12] · nH2O were tested in the hydrofining of light coker gas oil. The maximum activity was displayed by the catalysts prepared on the basis of the vanadium-containing heteropoly compounds H3[PVMo11O40] · nH2O and (NH4) x [V(MoO3)12] · nH2O.
