Experimental Investigation and Modeling of Carbon Dioxide Adsorption from Model Flue gas


دانشکده مهندسی شیمی


In this work, the adsorption of carbon dioxide from model flue gas on different adsorbents has been investigated. Using simplified modeling, parameters such as the total mass transfer coefficient and the effective diffusivity have been determined. Experiments were carried out in two sections: firstly, adsorption of pure carbon dioxide on different adsorbents was measured at pressures ranging from 30 to 120 kPa and a temperature of 25°C using a low pressure volumetric adsorption system. In this section, activated carbon, Norit RB3 and Eurocarbon showed significant uptake. Secondly, using a dynamic adsorption system, the breakthrough curve of carbon dioxide was obtained from a column with an inner diameter of 1 cm and a length of 28 cm. The calculated standard experimental error was 0.19. This error showed that the applied model is suitable for predicting adsorption of carbon dioxide from model flue gas.
