Molecular Sieve Types and Structures

Ⅰ. There are two types of molecular sieves: natural zeolite and synthetic zeolite.

1. Most natural zeolites are formed by the reaction of volcanic tuff and tuffaceous sedimentary rocks in marine or lacustrine environments. At present, more than 1,000 kinds of zeolite minerals have been discovered, of which 35 are more important. The common ones are clinoptilolite, mordenite, erionite and chabazite.
