ABSTRACT

Dynamic adsorption is a mass-transfer process analyzed with complex calculations, where various parameters established by independent batch kinetic studies or estimated by suitable correlations are required. To make use of adsorption unitary operations, usually a reactor, where a dynamic adsorption process takes place, is packed with a concrete adsorbent. The adsorption process is supposed to be very fast relative to the convection and diffusion effects, subsequently local equilibrium will exist close to the adsorbent beads. In this regard, the adsorbents mainly used in these applications are zeolites, silica, mesoporous molecular sieves, carbon adsorbents, alumina, clays, Prussian blue analogues, nitroprussides, porous polymers, metal organic frameworks, and akaganeites. Some of the following conditions are needed for an appropriate performance of the adsorption reactor those are Residence time, Particle size and Reactor longitude. Moreover, it is considered that the fixed-bed adsorption reactor is packed randomly using adsorbent particles, fresh or regenerated.
