3A molecular sieve is a kind of potassium sodium aluminosilicate. Because its pore size is only 0.3 nanometers, it can selectively adsorb substances with molecular sizes smaller than 0.3 nanometers. Among them, the "A" of the molecular sieve represents the pore size, so the pore size of the 3A molecular sieve is 3Å. 3A molecular sieve can efficiently adsorb small molecular organic substances such as ethanol, acetone, and methanol.
In petroleum and chemical industry, 3A molecular sieve is mainly used as desiccant. In the gas-liquid phase deep drying, 3A molecular sieve can absorb the water molecules in the gas, so that the gas becomes more pure and dry. In the process of refining and polymerization, 3A molecular sieve can be used to remove water molecules in the reaction system to maintain the effectiveness and stability of the reaction.Due to its highly selective and efficient performance, 3A molecular sieves are widely used in various applications.
