Eco-friendly CO2 adsorbent by impregnation of diethanolamine in nanoclay montmorillonite

In this study, modification of the nanoclay montmorillonite adsorbent with diethanolamine and optimization of CO2 adsorption operating conditions to improve the adsorption capacity were carried out experimentally. The temperature, pressure, and weight percent of diethanolamine were considered in the range of 30−70 °C, 1−9 bar, and 10−30%wt, respectively, as input variables and adsorption capacity (mg/g) and adsorption percentage were considered...
