Product details

Typical Chemical Formula:

K12 [(AlO2) 12(SiO2) 12] · X H2O

Molecular sieve 3A is made by 3A zeolite powder with attapulgite clay, it is potassium form of type A zeolite crystal structure with an effective pore opening of about 3 angstroms (0.3nm).

Molecular sieve 3A adsorbs molecules with effective diameters smaller than approximately 3 angstroms. But excludes larger molecules such as unsaturated hydrocarbons and highly polar alcohols such as methanol and ethanol.

Molecular sieve 3A product by Luoyang Jalon exhibits high mass transfer efficiency, high mechanical strength and durability.


- Used for drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadiene).

- Used in deep desiccation of cracked petroleum gases, such as ethylene, propylene, butadiene, acetylene and natural gas, and of polar liquid, such as ethanol, LPG and solvent.

-Used in drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.

- Used in drying of highly polar compounds, such as methanol and ethanol.

- Used in drying of refrigerants (e.g. R22, R134a etc).

- Used in dehydration of benzene, toluene, xylene and other solvents.

- Used in static, (non-regenerative) dehydration of insulating glass units.

Keep 3A molecular sieve in an air tight container until ready for use to avoid unintended moisture adsorption.

Regeneration & Activation:

Molecular sieve 3A can be regenerated or activated either thermal regeneration method (Thermal Swing Adsorption, TSA); To remove moisture from a 3A molecular sieve, a temperature of 200-230°C (390-570°F) is required. Molecular sieve 3A can also be regnerated or activated by lowering the pressure in the case of pressure swing processes (PSA). A properly regenerated or activated molecular sieve can give moisture dew points below -100°C. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.

The manufacturing of molecular sieve is much easier, we add some binders to the synthetic zeolite powders with certain rate, usually we use Attapulgite clay and Kaolin clay as the binders. And also we will add some water. If we need bead products, we will put the well mixed synthetic zeolite and binders to the rolling machine, and the powders will be formed to bead, the diameter of the bead will be well controlled arrcording to the customers’ need, this is called products’ beading, after the beads are pre-dryed in the air, we will put the beads to the calcination oven, after calcination, we got the hot products, only after beads are cooling for a short time and packing, we got the final bead products; if we need pellet products, we will put the well mixed synthetic zeolite and binders to the pelleting machine, arrording to customers’ needs, we will choose the 1/8''1 or /16'' pellet, after pelleting, we put the pellets into the calcination oven, in the exit of the oven, we got the final pelleting products, after packing, it can be sold.
