“…This includes lower energy consumption, higher throughput and superior recovery and purity of products (Rezaei & Webley 2009;. Yu et al applied the principle on an activated carbon monolith (Cheng et al 2002;Yu, Luo, & Grevillot 2007;Yu, Luo, & Grévillot 2004) and two groups leaded by Grande Grande, Ribeiro, Oliveira, & Rodrigues 2009;Grande & Rodrigues 2008) and Ribeiro (Ribeiro, Grande, & Rodrigues 2012;2013; have intensively researched and employed ESA process for CO 2 capture on various types of monoliths. Considering the heat is electrically generated, the ESA process for CO 2 capture depends on the availability of adsorbents with high CO 2 capacity and selectivity and good electrical conductivity.…”

The goal of this work was to develop a 3D model of Electric Swing Adsorption pro- cess for carbon dioxide capture from effluent gasses from power plants. Detailed 3D model of the composite honeycomb monolithic adsorber was developed for a sin- gle monolith channel and can be used to simulate and represent different physical properties: velocity, concentration and temperature. The advantage of this model is the fact that all physical properties and results can be presented visually in the 3D domain. COMSOL Multiphysics software was used for solving partial differential equations and simulations of adsorption and electrothermal desorption processes. Some simulation results are presented in this work. The results obtained from 3D simulations will be used for the adsorber model reduction to the 1D model which will be used for modeling and optimization of the whole ESA cycle due to its sim- plicity and computational demands. Simulation and optimization runs based on the 1D model will be performed in g-Proms software.

CCS, Carbon Capture and Storage, is considered a promising technology to abate CO2 emissions from point sources. The present review deals with the principle of postcombustion capture techniques, including thermal or pressure swing principles, adsorption or absorption, and electrical swing or membrane separation processes.Opportunities and challenges are assessed. In the first section of absorption processes, several commercial technologies are compared, and complemented by the aqueous or chilled ammonia (NH3) process, and a dual or strong alkali absorption. The second section deals with adsorption where fixed beds, circulating fluidized beds and countercurrent bed configurations will be discussed, with special focus on the different adsorbents ranging from zeolites or activated carbon, to more complex aminefunctionalized adsorbents, nanotubes or metal organic frameworks (MOFs), and alkali-

On a obtenu des données expérimentales pour l'adsorption de l'acétate d'éthyle présent dans l'air à l'aide de tamis moléculaires 5A et 13X, en faisant varier la concentration d'adsorbat et la vitesse d'entrée ainsi que le rapport entre le diamètre et la longueur de lit, afi n d'étudier leurs effets sur la performance du lit adsorbeur. Un modèle mathématique reposant sur l'approximation de la force motrice linéaire est validé avec les données expérimentales et simulé pour comprendre les effets d'autres paramètres pertinents tels que le coeffi cient de transfert de matière global, la capacité de saturation et le coeffi cient de transfert de chaleur entre le lit et la paroi. Le tamis moléculaire 13X d'une capacité supérieure à celle du 5A se montre plus près du comportement d'adsorption idéal. Le taux de transfert de matière est contrôlé par la diffusion dans les pores.
