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

…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.
