Adsorption of ethyl benzene on activated carbon from supercritical CO2

Our work involves experimental and simulation studies of the adsorption bre akthrough and equilibria of ethyl benzene (a pollutant commonly encountered in industrial waste streams) on activated carbon in the presence of superc ritical carbon dioxide. Frontal and single breakthrough saturations were an alyzed for a range of operating conditions of pressure (100-130 bar) and te mperature (313-338 K). The equilibrium data correlated well with the Langmu ir isotherm. The adsorption process was successfully modeled by a three-par ameter model with comparable fitting parameters for the two types of breakt hrough curves.
