4A Molecular Sieve (4A Zeolite)

Product Detail

Summary

 

The pore size of 4A molecular sieve is 4a, which adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene and propylene. It does not adsorb any molecule (including propane) with a diameter greater than 4a, and its selective adsorption performance for water is higher than any other molecule. It is one of the most widely used molecular sieves in industry.

Matters needing attention

Molecular sieves should be prevented from absorbing water, organic gas or liquid before use, otherwise, they should be regenerated.
