Calcium type A (5A) Zeolite

Performance

I plant the production of 5A zeolite, sodium form of the Type A crystal structure, critical diameter can be adsorbed The 4A molecular formula is Ca45Na3 [AIO2 12 (SiO2), 12] · XH2O.

Use

Purification equipment for air, oxygen, oxygen-nitrogen separation, n-paraffins separation of the net system of natural gas, and through a selective adsorption process, and is separated from the hydrocarbons and cyclic, branched key n-paraffins, is currently used in the industrial large-scale pressure-alkane separation process, where it can be adsorbed on. 3A, Zeolite 4A, molecules can be 5A by the adsorbent.

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.
