dc.descriptionThe modelling and experimentation approach adapted in this study is simpler, straightforward and better suited than the original graphical technique commonly used for dynamic simulation of activated carbon adsorbers and it have been confirmed to be suitable for parametric studies of this kind from related studies (Alhassan et al. 2017; Chou and Chiou 1997; Yoro et al. 2017). The outcome of this study is expected to provide useful information that could be used to optimize polyaspartamide as an adsorbent for effective CO2 capture.en_ZA
dc.description.abstractParametric effect of moisture and influence of operating variables on the adsorption behaviour of polyaspartamide during CO2 capture was investigated in this study using experimental and modelling approach. Individual effects of operating conditions (e.g. pressure, temperature and gas flow rates) as well as the effect of moisture on the adsorption capacity of polyaspartamide were methodically investigated using Dubinin–Raduskevich model. Results from the investigations reveal that the presence of moisture in the flue gas had an incremental effect on the adsorption capacity of polyaspartamide; thereby showcasing the potential of polyaspartamide as a suitable hydrophilic material for CO2 capture in power plants. In addition, pressure, temperature and gas flow rates at 200 kPa, 403 K, and 1.5 mL/s, respectively, significantly influenced the CO2 adsorption capacity of polyaspartamide. Physisorption and chemisorption both governed the adsorption process while equilibrium studies at different temperatures showed that Langmuir isotherm could adequately describe the adsorption behaviour of the material with best fit with R2 > 0.95.en_ZA
