Application

Zeolite, a microporous, aluminosilicate mineral, is used as a molecular sieve and as an adsorbent of a wide variety of cations, such as Na+, K+, Ca2+, Mg2+ and others. Zeolite is used in the development of a variety of bioreactor devices.

General description

Regeneration or Activation:A 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 ways:1. Thermal reactivation –The maximum regeneration temperature for Silica is 300°C.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.

Choosing a Molecular Sieve:1. The preferential adsorption of one molecule over another depends upon pore diameter and mesh size.2. The dynamic capacity of the silica gel for adsorbing a particular compound is governed by the internal surface area; the greater the surface area, the greater the dynamic capacity.3. Rate of adsorption and sharpness of resolution are dependent chiefly on particle size and column packing; a fine particle size gives optimum sharpness of resolution.4. Liquids are most readily adsorbed from solvents in which they are least soluble; a good solvent makes a good desorbing agent.5. Highly polar liquids are readily adsorbed. Compounds having hydroxyl groups, or containing oxygen are strongly adsorbed.6. For similar compounds, the higher the molecular weight the higher the selectivity.7. For hydrocarbons of similar molecular weight, adsorptivity increases with the number of double bonds.
