Moreover, we studied the effect of pH and Cu(II) loading on adsorption performance and probed adsorption kinetics, thermodynamics and regeneration performance, revealing that modification of hierarchical ZSM-5 with Cu(II) not only significantly increased its TC removal efficiency but also allowed for good regenerability and suggested that the highly efficient and selective removal of TC from aqueous solutions could be ascribed to not only the strong interactions between Cu(II) and TC molecular but also the larger mesoporosity.

The overall performance of the post-combustion CO2 capture process has been evaluated from the results of the dynamic simulation of the process at cyclic steady state, using a detailed non-isothermal non-equilibrium dynamic fixed-bed adsorption model that takes into consideration competitive adsorption between the main flue gas components: N2, CO2 and H2O.
