The sodium X type (13X) zeolite

Performance

I plant the production of 13X zeolite, X-type crystal structure of the sodium-type the molecular adsorption critical diameter 10A, chemical formula for Naa86 [(CAIO2) 86 (SiO2), 106 XH2O.

Use

For general gas drying and net system in industrial air separation unit raw material purification (simultaneous removal of H2O and CO2), as well as liquid hydrocarbons and natural gas desulfurization (removal of H2S and mercaptans), or as a catalystcarrier. Where adsorbed on 3A, 4A, 5A zeolite molecule can be 13X adsorbed.

Regeneration conditions

I plant the production of 3A, 4A, 5A, 13X molecular sieve available heating and purge or evacuated, renewable reuse.

1. the removal of moisture: available drying gas, such as nitrogen, air, hydrogen, saturated carbonized hydrogen was heated to 150-320 ° C in 0.3-0.5kg/m2 under pressure introduced into the molecular sieve bed, continuing for 3-4 hours, and then tothe sorber pass into the dry cold gas for approximately 2-3 hours, isolated air-cooled to room temperature.

2. the removal of organic material: the available steam from the molecular sieve, the first adsorbate alternative out, then heated to 1, and the regeneration may also be in the 200-350 ℃ superheated vapor or inert gas through the regeneration, (can not be used with the adsorbate.contact produce an explosive mixture of gas).

3. the removal of gaseous material removal method available vacuum regeneration.
