Two kinds of Molecular sieve

Molecular sieve has two kinds of types. One is natural zeolite the other is synthetic zeolite. Most of the natural zeolite by volcano tuff and tuffaceous sedimentary rocks in marine or lacustrine environment formed by reaction. Has been found to have more than 1000 kinds of zeolite ore and more important there are 35 species, common with oblique clinoptilolite, mordenite, erionite and chabazite and. Mainly distributed in the United States, Japan, France and other countries, China is finding has a large number of modernity and clinoptilolite zeolite deposits, Japan is the extraction of natural zeolites in most countries. Due to the limited resources of natural zeolite, from the beginning of 1950s, a large number of synthetic zeolite has been produced.
