Overview:
4A molecular sieve has a pore size of 4 angstroms and selectively adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, and propylene, while excluding molecules larger than 4 angstroms (including propane). It exhibits superior selectivity for water adsorption compared to other molecules. 4A molecular sieve is one of the most widely used types of molecular sieves in industrial applications.
Performance:
Precautions: Prior to use, molecular sieves should be protected from adsorbing water, organic gases, or liquids. Otherwise, regeneration is necessary.
