4A molecular sieve has an effective pore opening of about 4 ang stroms (0.4nm). 4.

Amolecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms andexcude 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.

4)Packed in small bags, it may be used simply as a packaging desiccant.

Regeneration Molecular sieve Type 4A can be regenerated by either heating in the case of thermal swing processes;or by lowering the pressure in the case of pressure swing processes.To remove moisture from a 4A molecular sieve, a temperature of 250-280°C is required.

A properly regenerated 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.
