摘　　要：制备了NiW/Al2O3-USL系列催化剂,采用XRD、NH3-TPD、UV-vis DRS(紫外-可见漫反射光谱)以及BET比表面积分析等多种技术对催化剂的基本物性进行表征,并以柴油为原料,在高压加氢微反装置中进行催化剂的加氢脱硫(HDS)活性评价。结果表明,在相同反应条件下具有适宜USL添加量的NiW/Al2O3-USL-1催化剂的加氢脱硫效果优于参比的商业加氢催化剂,并且所得柴油产品硫含量<10μg.g-1,满足世界燃油规范IV类的标准。Catalysts containing different contents of USL zeolite were prepared and their physicochemical properties were characterized by XRD, NH3-TPD, UV-vis DRS and BET. Catalytic behaviors of the catalysts were tested in a high-pressure fixed-bed reactor with diesel as feed. The results showed that hydrodesulfurization activity of NiW/Al2O3-USL-1 of appropriate USL content was higher than that of commercial RN-10 hydrotreating catalyst. Diesel oil product with sulfur content of below 10 μg · g^-1 was obtained, which met world diesel specification Ⅳ.
