Experimental, RSM modelling, and DFT simulation of CO adsorption on Modified activated carbon with LiOH.

This research investigates the enhancement of CO adsorption capacity through the use of modified activated carbon (AC) with LiOH, focusing on operational conditions and adsorbent properties. Response Surface Methodology (RSM) is employed to optimize process parameters for maximizing CO adsorption capacity. The study considers temperature, pressure, LiOH concentration for modification, and adsorbent weight as independent variables across five levels.

Lithium hydroxide as a high capacity adsorbent for CO capture: experimental, modeling and DFT simulation.

In this work, the potential of monohydrate Lithium hydroxide (LiOH) as a high capacity adsorbent for CO capture was investigated experimentally and theoretically. The effects of operating parameters, including temperature, pressure, LiOH particle size and LiOH loading, on the CO capture in a fixed-bed reactor have been experimentally explored using response surface methodology (RSM) based on central composite design. The optimum conditions obtained by the RSM for temperature, pressure, mesh and maximum adsorption capacity were calculated as 333 K, 4.
