Adsorption Isotherms and Kinetic Models

Adsorption is a significant phenomenon that underlies a variety of crucial technical and environmental processes. There is no question about the importance of adsorption in protecting the environment and the industrial sector. Additionally, the first stage in many catalytic processes is adsorption of reactants over the catalyst. Therefore, numerous attempts have been made to explore the various adsorption process elements. However, a vital stage in the design and operation of adsorption equipment is having the working grasp of adsorption equilibrium and kinetics. To comprehend the adsorption equilibrium and kinetics, several different isotherms and kinetics models have been created. This chapter makes an effort to present an overview of a particular set of theories, isotherms and kinetic models used to describe adsorption events at the gas–solid interface. This chapter is split into two sections: the first section covers the theories and models (kinetics). The models that are used to analyze the isotherms of adsorption are the main topic of the second section.
