Industry 13X Molecular Sieve Desiccant For Gas Drying And Purification
13X Molecular Sieve Desiccant Introduction
13X molecular sieve is of the type X crystal, as opposed to the type A crystal of the 3A, 4A, and 5A molecular sieves. However, the 13X molecular sieve is similar to the 4A in that it has sodium ion (Na+) in its structure. The different types of the crystal affect the size of the pore opening. Where the 4A molecular sieve has a 4 angstrom pore opening, the 13x molecular sieve has a 10 angstrom pore opening.
It will adsorb everything 3A, 4A, and 5A molecular sieves will adsorb (since it has much larger pores) along with much larger molecules. When an impurity you may want removed is too big for the type A crystal sieves, the 13x molecular sieve can potentially adsorb it.
