The Role of Co-adsorption Molecular Sieve Manufacturing All Type A molecular sieve originates as Type 4A zeolite crystals. These 4A zeolite crystals can be treated to an ion exchange to create 3A or 5A molecular sieve. To create Type 3A zeolite, larger potassium ions exchange for smaller sodium ions within

Does Size Really Matter? What Size Affects There are numerous, unique functions performed every day that use molecular sieve to separate, dehydrate, and create desired product streams. These various functions can require different particle sizes of molecular sieve, whether beads or pellets, which is determined by the conditions of the

Molecular Sieve Process Optimization Featured in Biofuels International, May 2015 (volume 9, issue 3) Molecular sieve dehydration of ethanol uses a specialized molecular sieve to remove the water from the distillation/rectification of ethanol and water. Distillation can only remove water to approximately 5% of the total composition. Molecular sieve consists of tiny zeolite

3A, 4A, 5A, 13X… What’s the Difference?

Type A All molecular sieves are composed of sodium and aluminosilicate, which are grown to form a three-dimensional crystal structure. It’s this crystalline structure that allows molecular sieve to adsorb some molecules while rejecting other molecules that are too large to fit inside the crystal When A-Type crystals are
