| 摘 要： | 研究了在ZSM-5分子筛催化剂上的醛氨缩合生成吡啶的反应，考察不同硅铝比、不同活性物质如Pb、Co、Pt、Ni等离子改性以及Pb负载量对催化剂性能的影响，并对催化剂进行了FT-IR、XRD、SEM表征。结果表明，硅铝比在100～150之间，Pb负载量在2．0～4．0%；催化剂性能最好，吡啶及烷基吡啶的总产率可达90％。

| Abstract: | The aldehyde ammonia condensation on ZSM-5 zeolite catalyst was studied. Effects of reaction parameters such as Si/Al ratio, laden about Pb,Co,Pt,Ni, laden metal ions quantity were discussed and the ZSM-5 zeolite catalyst was studied by FT-IR,XRD,SEM. The results show that the optimized conditions under which the reaction is carried out at Si/Al ratio=100-150, loading Pb=2.5- 4.0%, the total yields of pyridine and alkylpyridine can be more than 90%. |
