Factory Price Synthesized Zeolite 4A Sphere 3-5mm For Natural Gas Drying
Introduction
zeolite 4a molecular sieve is an alkali alumino silicate; it is the calcium form of the Type 4A crystal structure. Type 4A zeolite molecular sieve has an effective pore opening of 4 angstroms (0.4 nm). It will adsorb molecules with a kinetic diameter of less than 4 Angstrom and exclude those larger.
Typical Chemical Formula
Na2O·Al2O3 ·2.SiO2· 4.5H2O
Application
1) Drying and removing of CO2 from natural gas, LPG, air, inert and athmospheric gases, etc.
2) Removal of hydrocarbons, ammonia and methanol from gas streams (ammonia syn gas treating)
3) Special types are used in the air break units of buses, trucks and locomotives.
4) Packed in small bags, it may be used simply as a packaging desiccant.
