I. Product Introduction
Our company's 13X molecular sieve is a sodium-type aluminosilicate with a crystal pore size of 9Å (0.9nm), capable of adsorbing molecules with a critical diameter no larger than its pore size.
II. Main Applications
Mainly used for drying general industrial gases, purification of raw materials in air separation units (simultaneously removing H2O and CO2 and some hydrocarbons), meeting the special requirements of the air separation industry, improving the adsorption capacity of H2O and CO2, avoiding the phenomenon of freezing towers in cryogenic air separation, and featuring high carbon dioxide adsorption capacity, low regeneration temperature, and long service life.
III. Storage Conditions
Dry, cool, and dark.
IV. Implementation Standards
Implemented according to the national standard HG/T 2690-2012 superior product indicators.
