摘　　要：介绍了一种按新方法制备的γ -Al2 O3 载体以及在该载体基础上研制开发的FW石蜡加氢精制催化剂的性能。PASCA、低温N2 吸附以及小型加氢实验装置等相关技术分析表征和试验评价的结果表明 ,FW新型催化剂具有优良的表面性质 ,活性组分 (MoO3 )在其表面上有较高的上载量和高的化学分散量 ,且具有较大的孔径 ,孔容和比表面积 ,孔分布集中 ,机械强度高 ,活性高 ,稳定性好和对原料蜡的适应性强等优点。在相同工艺条件下用于多种原料蜡的加氢精制 ,其加氢性能优于同类参比催化剂。This paper introduces the properties of γ-Al_2O_3 carrier prepared by a new method and FW catalyst based on the newly developed γ-Al_2O_3 carrier. The results, by using PASCA, N_2 physical adsorption and bench-scale tests, etc. show that FW catalyst has better surface properties, higher chemically dispersed amount of active components (MoO_3), larger pore diameter, pore volume and specific surface area, concentrated pore distribution, stronger mechanical strength, better adaptability to various wax feeds, higher hydrofining activity and stability. The newly developed FW catalyst is much better than the reference catalyst for its hydrofining activity for hydrofining various wax feeds under the same operation conditions.
