DehySorb Z3-02

Molecular Sieve Type 3A
Adsorbents

DehySorb Z3-02 molecular sieve is an alkali metal alumino-silicate. It is the potassium form of the A-type molecular sieve structure and has an effective pore opening of 3 Angstroms (0.32 nm).

DehySorb Z3-02 combines the controlled pore structure, high hydrothermal stability, and minimized sulfur, carbon dioxide, and hydrocarbon co-adsorption of 3A products with properties to reduce catalytic activity. It is widely used in applications where the formation of carbonyl sulfide must be minimized in the presence of CO2 and H2S.

DehySorb Z3-02 was developed and formulated for the drying of cracked gas and other gas or liquid streams containing unsaturated hydrocarbons, such as ethene, propene, and butene.

DehySorb Z3-02 will adsorb molecules with a kinetic diameter of less than 3 Angstroms and will exclude larger molecules.
