摘要
介绍了目前世界上存在的长链烷烃异构化反应的催化机理,列举了近年来研究者根据各自不同的研究背景,采用探针分子方法对该机理进行的研究,结果所支持的观点主要有择形催化、孔口催化和Key-Lock催化。根据存在的争议和研究现状对探针分子提出了新的构想,认为针对催化剂特殊的十元环孔道结构,寻求设计出具有特定结构的探针分子,通过这种探针分子,在SAPO-11分子筛负载的催化剂上进行异构化反应,根据反应结果数据对比,不需再进行模拟推测,能直接对孔口催化观点给出依据。
The mechanism of high alkanes in isomerization reaction were introduced.Under the different backgrounds,researchers took the method of probe molecules to study the mechanism.The main ideas they pointed were shape-selective catalysis,pore mouth catalysis and Key-Lock catalysis.According to the debates and the current situation,a new idea about the probe molecules was given in this article.
