In addition to these specialized adsorption designs there are a number of variations on regeneration and cooling processes. The pulse regeneration technique has been practiced for several decades. In this variation we introduce a pulse of hot purge gas over a somewhat limited duration and then follow that with a cooling...

The term adsorption designates the situation in which the molecules of a gas (the sorbate) are concentrated at the surface of a solid (the sorbent) with which the gas is in contact. The concentration results from an attractive potential experienced by the sorbate at the sorbent surface and is usually viewed as a temporary residence of sorbate molecules on the sorbent surface. The gas-solid interaction is the usual picture for adsorption, but it is not the only one possible the sorbate could be a dilute constituent in a condensed phase (e.g., gases dissolved in water), and/or the sorbent could be a liquid. 

Weber and Van Vliet [20] briefly described the Michigan Adsorption Design and Applications Model (MADAM), which includes both equilibrium and kinetic considerations, while Manes [729] advocated the use of the Polanyi adsorption potential theory, even to account for pH effects neither of these approaches includes a description of the role of carbon surface chemistry.

Before considering the specifics of adsorption design factors, it may be useful to generalize the process with some simplified analogies. 

Many adsorption design approaches assume that adsorption is occurring isothermally. This is a good assumption only when the adsorbable component concentration is low and/or the heat of adsorption is low. There are two simple methods that can be used to determine...

O-saturated surface of 0.70, demonstrating that sites for NH3 adsorption, designated below as s, are different from sites for O adsorption, designated However, once a significant proportion of the surface O adlayer has been consumed in the reaction, the product N2 is observed, and becomes dominant. By back-integration it was determined that N2 is only formed when the O coverage falls below 0.16 ML.
