摘要
以USY型分子筛为载体,通过浸渍法制备了Co-Mo/USY催化剂,采用XRD,NH3-TPD,H2-TPR等手段对催化剂进行表征,并用硫代硫酸铵对催化剂进行器外预硫化,在连续固定床反应器上考察了不同Mo负载量催化剂对煤焦油加氢裂化性能的影响。结果表明,催化剂的最佳Mo负载量(w)为12%,在反应温度385℃、压力9 MPa、质量空速0.6h-1、氢油体积比1 000∶1的条件下,煤焦油加氢裂化的轻质油收率为86%。
CoMo/USY hydrocraeking catalysts were prepared using USY molecular sieve as supportby using impregnation method and characterized by XRD, NH3-TPD, H2-TPR. （NH4）2S2O3 was used as a presulfidation agent. The performance of coal tar hydrocracking of catalysts prepared with different Mo loading was investigated by orthogonal test in a continuous flow fixed-bed reactor. The results indicate that the catalyst with 12% Mo is the best. The yield of fuel oil reached 86% under the reaction conditions of a temperature of 385 ℃, a pressure of 9 MPa, a WHSV of 0.6 h^-1 , and a H2/oil ratio of 1 000.
