Zeolite 4A

Zeolite 4A

A main component of A-type molecular sieve is aluminosilicate, silicon-oxy and alumina tetrahedron to form a LTA-type structure, the main crystal structure is eight membered rings. In zeolite 4a, sodium ion formation with a pore opening of 4Å (1Å=1×10-10m), that is type 4A (also known as NaA-type) molecular sieve.

Recommended Application of  zeolite 4a
 1. Drying of unsaturated  hydrocarbons (e.g. ethylene, propylene, butadiene)
 2. Cracked Gas Drying.
 3. Drying of natural gas.
 4. Drying of highly polar  compounds, such as methanol and ethanol.

Storage:
●Avoid moisture, avoid  scrolling, throw and sharp shocking during transportation, rainproof facilities  should be readied..
●It should be stored in dry  and ventilated warehouse to prevent contamination or moisture.
