Abstract

The aim of this paper is to present a critical review on reactive adsorption processes. The impact of surface modification on adsorption behavior of various adsorbents in context of reactive adsorption has been reviewed. Various characterization and detection methods involved to access and verify the surface morphology of adsorbent, presence of surface functionalities on adsorbent, and concentration of adsorbate have been concisely presented. The paper also delves into the inadequately researched grey areas of reactive adsorption which require further attention such as modeling and adsorbent regeneration so as to make the process more economic. The applicability of reactive adsorption to ensure a cleaner environment has also been briefly discussed. This article also underlines the areas, in which reactive adsorption can be implemented on a pilot scale.
