Molecular sieves are materials with pores of uniform size and diameter that are similar in size to small molecules; used to separate molecules by size; available in various pore size ranges, with drying solvent indicators, etc.

Regeneration or ActivationA saturated molecular sieve can be restored to its original capacity by regeneration the principle of which involves changing the conditions surrounding the adsorbent to correspond to a very low equilibrium capacity. In general the greater the difference between the equilibrium capacities of adsorption and regeneration the more rapid and complete the regeneration.The sieve may be regenerated in one of four ways1. Thermal reactivation -The maximum regeneration temperature for Silica is 300C.2. Pressure reactivation3. Passing an appropriate fluid through the gel bed at normal temperature and pressure.4. Displacement of adsorbates by passing a high concentration of molecules in a fluid through the bed.
