Molecular sieves can be defined as substances with discrete pore structures that can

discriminate between molecules on the basis of size. Carbon molecular sieves

(CMS) are a special class of activated carbons. However, pore size distribution of

these materials is not always strictly discrete and furthermore, molecules are not

hard spheres; they can sometimes squeeze into narrow pores. The distinction

between activated or porous carbons and carbon molecular sieves is not clearly

defined. Carbon molecular sieves have most of the pores in the molecular size range

but some conventional activated carbons also have very small pores. The main

distinction is that activated carbons separate molecules through differences in their

adsorption equilibrium constants.

molecular sieves is that they provide molecular separations based on rate of

adsorption rather than on the differences in adsorption capacity. This behavior is

clearly evident in pressure swing adsorbers (PSA) where gas dynamics dominate.

The separation of nitrogen from air by PSA is the single most important application of

CMS.
