摘      要：Hydrodesulfurization(HDS)of sour crude oil is an effective way to address the corrosion problems in refineries,and is an economic way to process sour crude oil in an existing refinery built for sweet *** the current study,the HDS of Siberian crude oil was carried out in a slurry *** Co-Mo,Ni-Mo,and Ni-W catalysts supported onγ-Al2O3 were compared at the temperature of 340℃ and the pressure of 4.5 *** HDS activity follows the order of Co-Mo N Ni-Mo N Ni-Wat a high concentration of H2S,and the difference between Co-Mo and Ni-Mo becomes insignificant at a low concentration of *** influence of reaction temperature 320-360℃ and reaction pressure 3-5.5 MPa was investigated,and both play a positive role in the HDS reaction.A kinetic model over Ni-Mo/Al2O3 in the slurry reactor was *** activation energy is estimated as 60.34 kJ·mol−1;the orders of sulfur components and hydrogen partial pressure are 1.43 and 1.30,*** kinetic parameters are compared with those in a trickle-bed reactor,implying that the mass transfer is greatly enhanced in the slurry *** back mixing effect is present in the slurry reactor and can be reduced by a multi-stage design,which would lead to higher reactor efficiency in industrial application.
