采用浸渍法和离子交换法合成了CuO/SBA-15、CuAl/SBA-15和CuOAl/SBA-15 3种催化剂.SBA-15的酸功能通过负载A1而得以改进.通过浸渍法和离子交换法将Cu引入SBA-15和A1/SBA-15中.3种催化剂相比,CuAl/sBA-15在DeNPAC反应中具有最高的吡啶转化率的同时,具有最低的NOx产率.CuAI/SBA-15具有较好的含氮多环芳烃化合物脱除反应性能的原因,可能是其酸功能和金属离子功能共同作用的结果.
採用浸漬法和離子交換法閤成瞭CuO/SBA-15、CuAl/SBA-15和CuOAl/SBA-15 3種催化劑.SBA-15的痠功能通過負載A1而得以改進.通過浸漬法和離子交換法將Cu引入SBA-15和A1/SBA-15中.3種催化劑相比,CuAl/sBA-15在DeNPAC反應中具有最高的吡啶轉化率的同時,具有最低的NOx產率.CuAI/SBA-15具有較好的含氮多環芳烴化閤物脫除反應性能的原因,可能是其痠功能和金屬離子功能共同作用的結果.

CuO/SBA-15, CuAI/SBA-15 and CuOAI/SBA-15 were synthesized by wet-impregnation and ion-exchange methods. The acidic properties of SBA-15 were improved by incorporating AI with post-synthesis method. The Cu was introduced to SBA-15 and AI/SBA-15 supports by wet-impregnation and ion-exchange method, respectively. CuAI/SBA-15 showed the best catalytic performance by giving the highest conversion of pyridine with the lowest yield of NOx in the reaction of decomposing nitrogen-containing polycyclic aromatic compounds (DeNPAC). The enhanced reaction activity of CuAl/SBA-15 for DeNPAC could be attributed to the hi-functionality of acid and metallic ion of CuAl/SBA-15.
