Investigation of Equilibrium Adsorption of Gases on Solid Adsorbents

Adsorption of gas on solid adsorbents is one of the important processes in gas industry and industrial wastewater treatment processes. In this work، the equilibrium adsorption models of gas on solid adsorbents are studied in order to investigate the absorption system behavior and predicting the amount of absorption. Moreover، after introducing two and three parameter models of equilibrium gas absorption on solids، Langmuir، Freundlich، Temkin and Redlich- Peterson models have been investigated. After mathematical formulation of these models، the tuning parameters have been adjusted. In order to investigate the performance of each model، the deviation from experimental data has been calculated. The results show that Freundlich and Redlich- Peterson models predict the gas adsorption experimental data on adsorbents more accurately in comparison to other models. Also، the Temkin model predicts the gas adsorption experimental data on solid adsorbents more accurately in comparison to Langmuir model.
