Molecular Sieve Water Adsorbent 13X Zeolite balls With High Quality
Introduction
Molecular Sieve 13X is the sodium form of the type X crystal and has a much larger pore opening than
the type A crystals. It will adsorb molecules with a kinetic diameter of less than 9 Angstrom (0.9 nm)
and exclude those larger.
It also has the highest theoretical capacity of the common adsorbents and very good mass transfer rates.
It can remove impurities too large to fit into a type A crystal and is commonly used to separate nitrogen
from oxygen.

Application
Molecular sieve 13X is applied in the desiccating process of industrial gas and gas purification in air separation unit ,mainly aiming for the removal of H2O,CO2 and hydrocarbon gases. To meet the special requirements of the cryogenic air separation industry, we improve the ability to absorb carbon dioxide and water so as to avoid the occurrence of cold tower phenomenon in air separation process. Molecular sieve 13X has the characteristics of high CO2 adsorption capacity, low regeneration temperature and long service life. Natural gas, liquefied petroleum gas, liquid paraffin (propane, butane) dehydration and desulfurization (removal of H2S and mercaptan). The deep drying of general gas (such as compressed air, permanent gases) Ammonia synthesis gas drying and purification. Desulfurization aerosol propellant deodorant. The cracking gas from CO2.
