Exploiting response surface methodology for experimental modeling and optimization of CO2 adsorption onto NaOH-modified nanoclay montmorillonite

In this work, operational conditions and adsorbent properties of modified montmorillonite nanoclay (MMT) with NaOH were investigated to improve CO2 adsorption capacity. To optimization the adsorption operational conditions, process factors e.g. reactor temperature and pressure, acid concentration for activating the surface and wt% NaOH for surface modification were evaluated through five level four factor central composite design (CCD) using...
