Principle & Application

 

A molecular sieve is a material with very small holes of precise and uniform size. These holes are small enough to block large molecular while allowing small molecular to pass. Molecular sieve has a very wide range of applications, can be used as a efficient desiccant, selective adsorbent, catalyst, ion exchange, etc., mainly used in automobile, building glass, medicine, paint, packaging and other fields.

 

Type

 

3A, 4A, 5A, 13X molecular sieve, Insulating glass molecular sieve, Air separation special molecular sieve etc.

 

Regeneration

 

1.       Methods for regeneration of molecular sieve include pressure change (as in oxygen concentrators), heating and purging with a carrier gas (as when used in ethanol dehydration), or heating under high vacuum.

 

2.       Regeneration temperatures range from 175to 315depending on molecular sieve type. In contrast, silica gel can be regenerated by heating it in a regular oven to 120(250) for two hours.

 

3.       However, some types of silica gel will popwhen exposed to enough water. This is caused by breakage of the silica gel spheres when contacting the water.
