Description
A molecular sieve is a material with pores (very small holes) of uniform size. These pore diameters are similar in size to small molecules, and thus large molecules cannot enter or be adsorbed, while smaller molecules can.Manufacturers of molecular sieve 4Ao , which has gained wide appreciation for its quality standards. Having a diameter of four angstroms, this sieve is widely used to adsorb methanol, ethanol, sulfurated hydrogen, carbon dioxide, ethylene, propylene and water.
