A systematic analysis of the dynamics of microwave- and conventionally-assisted swing adsorption on zeolite 13X and an activated carbon under post-combustion carbon capture conditions

This work presents a detailed parametric experimental on the feasibility of microwave regeneration two commercial adsorbents in dynamic carbon capture swing adsorption system. A synthetic flue gas (15% v/v CO2 N2) dry or with 15% relative humidity was selected, along Norit R2020CO2 activated and zeolite 13X. purpose-modified apparatus used to compare microwave-assisted conventional thermal regeneration. The impact operating parameters process performance measured for heating. Parameters considered were type adsorbent, composition, quantity adsorbent (and bed size), time full regeneration, capacity, recovery, purity desorption kinetics. Results showed that advantages over its equivalent, as purity, productivity found be higher under former studied. For needed achieve 50, 80, 90, 99% benefits conductive increased an increase sample size. Under wet feed, 13X appreciably working capacity than (39.68 24.23% higher, respectively). also maintained heating opposed (9.36 20.39% larger observed is attributed better
