Abstract
This chapter addresses the CO2 adsorption kinetics and equilibria of LDH and LDH/GO hybrids under dry and wet conditions using breakthrough curve responses obtained in a fixed-bed column. A comparative study between temperature-swing and isothermal N2 purge experiments is presented. In addition, a mathematical model based on the linear driving force approximation is used to describe the dry experiment profiles.

The optimal estimated value of kLDF was found with the gPROMS in-built parameter estimation facility based on a Maximum Likelihood formulation. The 95 % t-value was ≫ 95 % reference t-value in all cases. In addition, the confidence intervals were ≪ respective estimated parameter value.
