Molecular Sieve for Liquid Drying
1.The types of molecular sieves are mainly divided into: A type, X type according to their crystal structure.
2.It can withstand short-term high temperatures of 600-700 °C, but the regeneration temperature is generally below 400 °C
2.It is widely used in metallurgical,chemical,electronic, petrochemical,natural gas and other industries.
Product Introduction
Molecular sieves (also known as synthetic zeolites) are aluminosilicate microporous crystals, which are composed of SiO and AIO tetrahedra and have a framework structure.
Metal cations (such as Na, K, Ca, etc.) are present in the zoelite lattice to balance the excess negative charges in the tetrahedron.
The main component of type A is aluminosilicate, with a pore size of 4A (1A=10 -10 m), which is called 4A (also known as nano-A) kind; the Na+ in the 4A kind is exchanged with Ca2+ to form a pore size of 5A, which is 5A (also known as calcium type A) zoelite sieve; exchange Na+ of 4A zeolite with K+ to form the pore size of 3A, which is 3A (also known as potassium A type) zeolite sieve.
The crystal structure of X-type aluminosilicate is different (the ratio of silicon to aluminum is different), forming molecular sieve crystals with a pore size of 9-10A, which is called 13X (also known as sodium X-type) ; exchange Na+ in 13X with Ca2+, A molecular sieve crystal with a pore size of 9A is formed, which is called 10X (also known as calcium X type) zeolite sieve.

Character of Service
Strong ability of molecular sieve hygroscopic, used for gas purification processing, should be avoided when saving deposit directly exposed to the air for a long time and has hygroscopic and should be done before the molecular sieve using regeneration of molecular sieve avoid oil and liquid water use should avoid contact with oil and liquid water dry processing of the gas in the industrial production, air, hydrogen, oxygen, nitrogen, argon, etc. With two adsorption dryer in parallel, a job, at the same time, the other one can undertake work alternates regeneration process and regeneration, to ensure the equipment run continuously dryer work under 8 to 12, air flushing regeneration under heating to 350The regeneration temperature of molecular sieves with different specifications is slightly different. The molecular sieves have good catalytic effect on some organic gases.
