INTRODUCTION

y In several process for separating gaseous or liquid

mixture, the fluid is contacted with small particles

of a porous solid which selectively adsorbs or

complexes with certain components of the Feed. Inadsorption the solid is usually held in a fixed bed,

and fluid is passed through the bed until The solid

is nearly saturated

THEORYOF ORPTIONAdsorption is a process that occurs when a gas or liquid

solute accumulates on the surface of a solid or a liquid(adsorbent), forming a molecular or atomic film (theadsorbate).

Physisorption or physical adsorption is a type of adsorptionin which the adsorbate adheres to the surface onlythrough Vander Waals (weak intermolecular)interactions, which are also responsible for the non-idealbehavior of real gases.

Chemisorption is a type of adsorption whereby a moleculeadheres to a surface through the formation of a chemicalbond, as opposed to the Vander Waals forces which causephysisorption.
