| 摘 要： | 考察了助剂B对含硅NiMo/Al2O3催化剂孔结构及表面酸性的影响，制备出一种孔容和比表面积大、孔分布集中、金属分布均匀和酸性适宜的加氢精制催化剂。分析结果表明，B的加入可以改善含硅氧化铝载体及催化剂的孔结构及表面酸性，有利于C—N键的断裂，从而提高催化剂的加氢脱氮性能。活性评价结果表明，采用适量B助剂改性的加氢处理催化剂具有高的加氢脱氮活性和稳定性。

| Abstract: | The effects of doping of B on pore structure and surface acidity of Si-containing NiMo/Al2O3 hydrofining catalyst were investigated.A hydrofining catalyst was prepared with high pore volume,high surface area,centralized pore distribution,uniform metal distribution and appropriate acidity.The results showed that addition of B improved pore structure and surface acidity of the support and catalyst and hence enhanced its HDN activity.200 mL bench-scale test showed that the hydrofining catalysts modified by appropriate amount of B had higher HDN activity and stability. |
