Zeolite and zeolite can be divided into two major categories of synthetic zeolite. Mainly used as synthetic zeolite catalyst, the application has more depth. Natural zeolite was first discovered in 1756, the Swedish mineralogist, and because of their superior thermal stability of synthetic zeolite, acid resistance, radiation resistance, and low cost, large reserves, and other characteristics, has become attached great importance to the world The new mineral resources, and more and more attention [1]. China is a country rich of natural zeolite. Origin of the natural zeolite has been found mainly in China's 21 provinces, autonomous regions, a total of 150 multiple origin of zeolite rocks. According to incomplete statistics, the current annual output of 800 million t of zeolite about.
Zeolite is the zeolite group minerals in general, widely distributed in the crust. A moisture content of alkali metal or alkaline earth metal aluminosilicate frame-like structure. The natural zeolite has been found about 40 species of common are: clinoptilolite, hair zeolite, mordenite, Hui zeolite, zeolite and Ling zeolite films. Its internal cavity and contains many channels. Zeolite has a large surface area (400 m2 / g ~ 800 m2 / g), and the balance on the zeolite framework structure with Debu cation and close easily with the aqueous cation exchange, which zeolite has a good adsorption and exchange properties.
