5A Activated Molecular Sieve-Spherical & Bar shape
5A Activated Molecular Sieve-Spherical & Bar shape
Introduction & Specs
| Introduction | 5A molecular sieve is an alkali metal aluminosilicate with a pore size of 5Å and a calcium-type A-type crystal structure. It can absorb any molecule with a diameter smaller than 5Å. In addition to the properties of 3A and 4A molecular sieves, it can also adsorb C3-C4 normal alkanes, ethyl chloride, ethyl bromide, butanol, and other hydrocarbons. |
| Benefits | l High selectivity
l Fast adsorption rate l Especially suitable for pressure swing adsorption |
| Applications | l Pressure swing adsorption units of various sizes for oxygen, hydrogen, and carbon dioxide production
l Air purification, dehydration, and carbon dioxide removal l Natural gas drying, dehydration, and desulfurization l Separation of normal and iso-alkanes |
| Molecular formula | 0.7CaO·0.3Na2O·Al2O3·2SiO2··4.5H2O (SiO2:Al2O3≈2)
