13X Molecular sieve , also called zeolite 13X , is one type of aluminosilicate crystal with average pores measuring of 9 angstrom (0.9 nm). Molecular with kinetic diameter smaller than 9 angstrom will be adsorbed by zeolite 13X, otherwise be excluded.
5A molecular sieve, generally also known as zeolite 5A ,it is a kind of molecular sieve with an effective pore opening of 5 angstroms, can absorb any molecule with kinetic diameter smaller than 5 Angstrom and exclude those larger. In addition to the functions of 3A and 4A molecular sieves, it can also adsorb C3-C4 normal alkanes, chloroethane, bromoethane, butanol, etc., and can also be used for the separation of normal isomers, pressure swing adsorption separation and the co-adsorption of water and carbon dioxide.
4A molecular sieve is a kind of potassium-sodium aluminosilicate with LTA-type skeleton structure which is composed of silicon-oxygen and aluminum-oxygen tetrahedrons.The main crystal hole of the 4A molecular sieve is an eight-membered ring structure, and the crystal pore size is 4Å (0.4nm).It can adsorb water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene and propylene, but does not adsorb any molecule with diameter greater than 4A (including propane). Its selective adsorption performance for water is higher than that of any other molecule.It is one of the largest molecular sieves varieties in industry.It is widely used in the drying of gases and liquids, and also in the refining and purification of some gases or liquids, such as the preparation of argon.
3A molecular sieve,sometimes also known as 3A zeolite molecular sieve,is a kind of potassium-sodium aluminosilicate with LTA-type skeleton structure which is composed of silicon-oxygen and aluminum-oxygen tetrahedrons.The main crystal hole of the 3A molecular sieve is an eight-membered ring structure, and the crystal pore size is 3Å (0.3nm).This kind of Molecular Sieve is mainly used to adsorb water, and does not adsorb any molecule with a diameter larger than 3A. According to the characteristics of industrial applications, the molecular sieve 3A produced by Fulong has faster adsorption speed, more regeneration times, higher crushing strength and stronger wear resistance,which greatly improves the utilization efficiency of molecular sieves and prolongs the service life of molecular sieves. It is the first choice desiccant necessary for deep drying,refining and polymerization of gas and liquid phases in petroleum and chemical industries.3A molecular sieves are usually used in ethylene, propylene, butadiene, methanol, ethanol, natural gas, cracked gas, refrigerant dehydration, etc.
