BRIJ30模板剂对镍钼超细催化剂加氢脱芳烃性能的影响

 在超细NiO-MoO₃/TiO₂-SiO₂催化剂制备过程中引入模板剂聚氧乙烯十二烷基醚(BRIJ30)，采用TG-DTA考察模板剂的脱除，采用N₂吸附-脱附、XRD、HRTEM分析考察模板剂对催化剂的物化性质、结构特性的影响。采用微型固定床反应装置，以航空煤油为原料进行加氢脱芳烃反应，考察催化剂的催化活性和稳定性。结果表明，引入模板剂BRIJ-30所制备的NiO-MoO₃/TiO₂-SiO₂催化剂的比表面积明显扩大，孔结构改善，加氢脱芳烃活性提高。

Effects of BRIJ30 Template on the Catalytic Hydrodearomatization Performance of Super Fine Ni-Mo Catalysts

Super fine NiO-MoO₃/TiO₂-SiO₂ catalyst was prepared with BRIJ30 (poly vinyl oxygen lauryl ether) as template. The removal of BRIJ30 was investigated by TG-DTA, and the influences of BRIJ30 template on the chemical properties and structural characteristics of NiO-MoO₃/TiO₂-SiO₂ catalyst were investigated by the methods of N₂ adsorption-desorption, XRD and HRTEM. The hydrodearomatization reaction in a micro-reactor with kerosene as raw material was used to research the catalytic activity and stability of the NiO-MoO₃/TiO₂-SiO₂ catalyst. The experimental results proved that BRIJ30 template obviously expanded the specific surface area and improved the pore structure of the catalyst, so that the catalytic activity of the catalyst increased.
