Molecular Sieves
Molecular sieve (also called synthetic zeolite) is a kind of microporous aluminosilicate
crystal. Its basic skeleton structure consists of silicon oxide, aluminum oxide tetrahedral. There are metal cation in its crystal lattice (such as Na +, K +, Ca2 +, Li +, etc.), these cation can balance the excess negative charge. According to their type of zeolite crystal structure is divided into A type, X type, Y type. According to molecular sieve aperture size, there are 3A, 4A, 5A, 10X, 13X. 4A molecular sieve is Na-A molecular sieve, aperture 0.4nm; if Na replaced by K, aperture 0.3nm, is 3A molecular sieve; if over 1/3 Na replaced by Ca2+, aperture 0.5nm, is 5A molecular sieve.
Molecular sieve adsorption capacity come from physical adsorption (Van der Waals forces), its cavities have a strong polarity and coulomb field which show a strong adsorption capacity to polar molecules (such as water) and unsaturated molecules. Molecular sieve has a uniform pore structure, which can separate different polarity, different saturation, different sizes and different boiling molecules. It has the effect of "sieving", so called molecular sieves.
Yuanying molecular sieve has quick adsorption speed, excellent adsorption performance, high crushing resistance, strong pollution resistance, large specific surface areas, big pore volume, more regenerative times, strong thermal stability, very long lifespan.
There are the following types of products: 3A molecular sieves, 4A molecular sieves, 5A molecular sieves, 13X molecular sieves, insulating glass desiccant, refrigerant desiccant, clay desiccant, carbon molecular sieves.
3A Molecular Sieves
Yuanying 3A molecular sieve has quick adsorption speed, high crushing resistance, strong pollution resistance, more regenerative times and long lifespan.
3A molecular sieve, also called Kalium A molecular sieve, is Kalium ion alkali metal alumino-silicate compound. Its effective pore diameter is 3A (0.3nm), it can selectively adsorb those molecules in fluid which dynamic diameter is less than 0.3nm (such as water molecules, ammonia molecules), lets molecule dynamic diameter more than 0.3nm go through molecular sieve layer bed, and then achieve the aim of fluid mixture. 3A molecular sieve has small aperture, while adsorbs water molecules it can reject all other molecules, thus effectively avoid “total adsorption” phenomena. 3A molecular sieve is a kind of excellent desiccant used for adsorbing water mainly.
Application: Drying and purification of oil cracking gas; C2 and C3 fraction drying; ethylene, propylene, butylene, butadiene, pentane drying and purification; dehydration and purification of raw material of methane, ethane and propane; purification of liquid carbon dioxide; dissolved acetylene drying; water, air, gases, polar liquids (such as methanol, ethanol) and natural gas drying and purification; refrigerator drying; catalyst support; etc. 3A molecular sieve are widely used in petroleum refining, petrochemical, chemical industry, metallurgy, electronics, defense, etc., while in pharmaceuticals, light industry, agriculture, environmental protection and many other aspects, has increasingly been applied.
4A Molecular Sieves
Yuanying 4A molecular sieve is nonpoisonous and tasteless, no irritations to eyes and skin, does not cause allergies. 4A molecular sieve deposition in the soil after washing will not cause pollution, furthermore can improve soil, so it is a natural and environment-friendly product.
4A Molecular Sieve is a kind of synthetic, with micropore cubic lattice of alkali metal aluminosilicate salt. It also called Sodium A molecular sieve, its structure is similar to NaCl. Due to its effective pore diameter is 0.4nm, so it is called 4A molecular sieve, its space network structure is staggered by silicon-oxygen tetrahedron (SiO4) and aluminium-oxygen tetrahedron (AlO4). 4A molecular sieve decides the adsorption order according to the polarity of different molecules, adsorbs only those with a molecular diameter of less than 4A. For small polar molecules and unsaturated molecules, the greater polarity, the higher degree of unsaturation, the stronger of selective absorption.
4A molecular sieve adsorbs those substances which molecular diameter is less than 4A, such as water methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, ethane, propylene, ammonia, doesn’t adsorb molecules which diameter are greater than 4A (include propane), the selective adsorption performance to water than any other molecules.
4A molecular sieves application
(1) Argon gas making and purifying
(2) Detergent Builder: 4A molecular sieve as a detergent builder mainly used to exchange of calcium ions in water to soften water, remove dirt and prevent dirt deposition. 4A molecular sievesubstitute trisodium phosphate as detergent builder is a significant role on solving environmental pollution. 4A molecular sieve also is used for SOAP plasticizer, toothpaste abrasive, etc.
(3)Sewage Disposal: 4A molecular sieve as a softening agentinstead of domestic widespreadsulfonated coal, thereby reducing costs. In sewage 4A molecular sieves can remove ammonia nitrogen, Pb2+, Cu2+, Zn2+, Cd2+, etc. In addition to ensure water quality qualified, but also can recycle heavy metal.
(4) Metallurgical Industry separating agent:separation, extraction of potassium, rubidium and cesium in brine. In the industry it is used for collection, separation and extraction of metals and other processes.
(5) Petrochemical industry as catalyst, drying agent, adsorbent: depth drying gas and liquid such as air, natural gas, LPG, inert gas, hydrocarbons, saturated hydrocarbons, refrigerant; dehydrating agent for paint, polyester, dyesand coatings.
(6) For agricultural soil conditioner.
(7) Medicine forsilver zeolite antibacterial agent
(8) Static desiccant for household refrigerating systems, pharmaceutical packaging, automotive air conditioning, electronic components, easy to wet and deteriorate material, perishable chemicals.
(9) Used in the R-12 and R-22 system, molecules adsorbed by 3A molecular sieve can all be adsorbed by 4A molecular sieve.
5A molecular sieves
5A molecular sieve, also called Calcium A molecular sieve, non-toxic, odorless, nonflammable, non-explosive, insoluble in water and organic solvents, but soluble in strong acid and strong base. Its pore diameter is 5×10-10m, can adsorb any molecules which pore diameter is smaller than 5×10-10m. In addition to the effect of 3A, 4A molecular sieves, it also can adsorb C3-C4 n-alkanes, ethylene chloride, bromoethane, butanol, etc. 5A molecular sieve can be applied to pressure swing adsorption separation, heterogeneous hydrocarbon separation and coadsorption of water and carbon dioxide.
