Effect of modification of zeolite beta and introduction of its acid characterization technology

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.
