摘要
介绍了β沸石的结构和性能,举例说明不同改性方法(负载阳离子、水热处理、酸处理)都能起到改善β沸石催化性能的作用。利用酸性表征技术可以对改性前、后β沸石的酸性变化作出定性和定量分析。叙述了几种β沸石的酸性表征技术。
This paper introduces the structure and properties of β-zeolite,illustrates that the different methods of modification(loading cationic modification,treated by water or acid) can improve the catalytic activity of β-zeolite.Qualitative and quantitative analysis of acid changes of β-zeolite are performed before and after the modification by acid characterization technique.A more detailed introduction of several acid characterization techniques of β-zeolite is given in this paper.
