    Bulk molybdenum sulfide catalyst was prepared by thermal decomposition of ammonium heptamolybdate at 800 °C in a flow of a 10% (v/v) H2S/H2 gas mixture. Investigation of the catalytic activity of the grinding catalyst for hydrodesulfurization (HDS) of dibenzothiophene (DBT) was carried out in a batch magnetically stirring microautoclave reactor at 340 °C and 3 MPa H2. The influence of a wide range of H2S concentration on the catalytic activity was studied. A significant promoting effect on HDS of DBT by H2S was observed. The experimental results showed the great enhanced contribution from the hydrogenation route with H2S in HDS of DBT. However, severe inhibition by H2S against the direct desulfurization route was observed. Kinetic analysis leads to the individual reaction rate constant in the reaction scheme performed.

    A series of silica supported MoP(MoP/SiO2)catalysts with different Mo loadings were prepared by sol-gel method,followed by temperature programmed reduction treatment.The hydrodesulfurization(HDS)activity of the MoP/SiO2 catalysts was evaluated with thiophene and dibenzothiophene as model compounds.The influences of Mo loading,reaction pressure and temperature on the HDS activity were investigated.The catalysts MoP/SiO2 exhibit high activity for the HDS of thiophene and dibenzothiophene;the highest activity is observed over MoP/SiO2 with a Mo loading of 20%.An elevation of the reaction pressure or temperature can enhance the HDS of dibenzothiophene;however,it may also decrease the content of biphenyl in the products.

    The organic sulfur compound bis-(1, 1, 3, 3-tetramethylbutyl)-polysulfide was investigated as a novel sulfiding agent for hydrodesulfurization (HDS) catalyst by evaluating the conversion of dibenzothiophene (DBT) on a commercial Co-Mo/Al2O3 catalyst. The catalyst presulfided using the polysulfide in situ showed the same or higher activity than those using the conventional sulfiding agents dimethyldisulfide (DMDS) and CS2. The catalytic activity for HDS and hydrogenation depended remarkably on the presulfiding procedure such as type of sulfiding agent, temperature program in the presulfiding procedure, and in situ or ex situ method. The 35S radioisotope tracer method was used to elucidate the effect of various sulfiding operation parameters on sulfur behavior on the sulfided catalyst in the HDS reaction of DBT. The effects of sulfiding agent and temperature program on the catalytic activity mainly originate from differences in the amount of labile sulfur formed in the different sulfiding processes.
