| Abstract: | A series of novel hydrorefining catalysts of clover shape were prepared by an equivalent volume impregnation method of multi steps,using γ-Al2O3 containing SiO2 and/or TiO2 as composite oxide carrier and W-Mo-Ni as active metal components.The structure of the catalysts was characterized by means of XRF,BET,XRD,NH3-TPD,and their mechanical strength was measured.Evaluation of process conditions are as follows: reaction pressure 8 MPa,reaction temperature 340 ℃,hydrogen to oil volume ratio of 600∶1,volume space velocity of 1.5 h-1 with a hydrogenation unit in 100 mL fixed-bed reactor.The experiment results showed that the catalysts have the excellent catalytic performance of hydrodesulphurization(HDS),hydrodenitrogenation(HDN) and the olefin hydrogenation(HYD) for the inferior distillate fuel oil with high nitrogen content,with W-Mo-Ni/SiO2-TiO2-Al2O3 catalyst 98% HDS,97% HDN and 98% HYD were achieved. |
| Keywords: | hydrodesulphurization hydrodenitrogenation hydrogenation catalyst composite oxide carrier |
