| Abstract |
Electroactive biocarbon tubes filled up with diatomaceous earth pellets were set up in a tube array for the CO 2 separation through an Electric Swing Adsorption (ESA) cycle. The tube array was self-heated by applying voltage between its ends. The direct heating of the adsorbent material sped up the desorption step and thus quickly releasing an enriched CO 2 gas phase. The dynamics of the tube array ' s temperature and the CO 2 molar fraction in the gas phase adsorbent showed consistency when consecutive ESA cycles were performed. In order to define the conceptual design of the ESA cycle, the CO 2 competitive adsorption capacities were estimated for a set of CO 2 /N 2 gas mixtures ( <= 10% CO 2 ). The tubular adsorbent array essentially maintained its performance and structure when tested in the presence of air. The hybrid tube array demonstrated repeatability and stability for CO 2 separation through consecutive ESA cycles. The tube array configuration is advantageous in terms of the process scale-up and modular chemical process intensification in the agroindustry. |
