1. Molecular Sieve 3A Molecular Sieve type 3A is an alkali metal alumino-silicate; it is the potassium form of the type A crystal structure. Type 3A has an aperture about 3 angstroms (0.3nm). It doesn't absorb any molecules larger than 3A. It? used for absorbing water mainly. Yuanying Molecular Sieve 3A has quick absorption speed, high crushing resistance and pollution resistance, more regenerative times and long lifespan. It? the best desiccants for the deep desiccation, refining and polymerization of the gaseous phase and liquid phase in the petrochemical industry. Typical Chemical Formula: 0.45 K2O . 0.55 Na2O . Al2O3 . 2 SiO2 . nH2O 2. Molecular Sieve 4A Molecular Sieve type 4A is an alkali alumino silicate; it is the sodium form of the Type A crystal structure. 4A molecular sieve has an aperture about 4 angstroms (0.4nm). It doesn't absorb any molecules larger than 4A, including propane. It absorbs water, methanol, ethanol, sulfureted hydrogen, sulfur dioxide, carbon dioxide, ethylene, propylene mainly. Typical Chemical Formula: Na2O. Al2O3. 2 SiO2. n H2O 3. Molecular Sieve 5A Molecular Sieve type 5A is an alkali alumino silicate; it is the calcium form of the Type A crystal structure. Type 5A has an aperture about 5 angstroms (0.5 nm). It absorbs any molecules less than 5A. It is especially used in separation of the normal and isomerous alkane, Pressure Swing Absorption for gas, co-absorption of moisture and carbon dioxide. It is widely applied in different kinds gas PSA equipment. Typical Chemical Formula: 0.7 CaO. 0.3 Na2O.
