摘要:  采用酸沉淀法制备大孔γ-Al为载体,并用浸渍法制备NiP(25%)/γ-A1催化剂。BET、XRD、压汞法的分析结果显示:合成大孔γ-Al2O3载体晶型良好,且具有适宜比表面积和孔结构。催化剂经原位还原处理后,以柴油为原料在连续固定反应装置上,考察了催化剂的制备条件及反应条件对催化剂加氢脱硫活性的影响。结果表明:当载体合成温度为80℃,反应pH为8,反应条件为温度360℃、压力4.0MPa、空速1.0h-1、氢烃体积比500∶1时,催化剂的加氢脱硫活性最好,柴油的脱硫率可达98.2%。

Abstract: Using large pore γ-Al2O3 prepared by acid precipitation, the Ni2P(25%)/γ-Al2O3 catalyst was prepared as the support by the impregnation method. The test results of XRD, BET and mercury porosimetry show that the large pore γ-Al2O3 has preferable surface area and pore structure. After in-situ reduction,the effects of preparation conditions and reaction conditions on dehydrocracking activity of the catalyst were studied in a fixed-bed down-flow reactor with the diesel as the material. The results show that desulfurization degree of 98.2% would be attained under the optimum condition as follows: synthesis temperature of 80 ℃, pH of 8,reaction temperature of 360 ℃,reaction pressure of 4.0 MPa,liquid hourly space velocity of 1.0 h-1 and volume ratio of hydrogen to cyclohexane of 500∶1.
