Product Description

Introduction:

Molecular Sieve 4A is an alkali alumino silicate; it is the sodium form of the Type A crystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm). XINTAO type 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger. Such adsorbable molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxyde and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.

Advantages of molecular sieve 4A:

1) With uniform pore size and high surface area, thermal stability, high absorption capacity, high strength characteristics.

2) By molecules of different size and shape, select the adsorption, meaning that just absorb less than the pore size of 4A molecular sieve.(never adsorb any molecular larger than 4A)

3) For small polar molecules and unsaturated molecules, with selective absorption properties, the greater the polarity, the higher the unsaturation, the selective adsorption is stronger.

4)Has strong water absorption. Even at the higher temperature,Greater airspeed and the lower content of water, still have the relatively high water absorption capacity

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

Typical Chemical Formula

Na₁₂[(AlO₂)₁₂(SiO₂)₁₂]·XH₂O

Reactivation:

1. Removal of water: Hot gas at 200-350°C and pressure 0.3-0.5Kg/cm² flows through the Zeolite bed for 3-4 h. let temperature decreases down to 110-180°C, cooling.

2. Removal of organics: Regeneration is achieved by means of steam treatment to remove organics, and then remove water with method 1.

Conservation:

Room temperature, humidity <90%, non-expose to air; non-contact with water, acid and alkali.

Packing: 25kg & 30kg/CNT; 125-150kg/Drum; Palletized + plastic film wrapped; Inside PP airtight

Payment Terms:	L/C,TT.etc
