CO2 removal from multi-component gas mixtures by adsorption processes

Carbon dioxide capture, whether from natural gas streams or from flue gases, is an important and increasing area of research with significant implications for our economy and environment. This research looked at the use of novel materials for improved C02 capture efficiency, including zeolites and metal organic frameworks (MOFs). Extensive experimental data, using advanced instrumentation, was acquired for each combination of adsorbent and adsorbate, particularly for multi-component (C02+CH4 +N2) systems, to test the predictive capabilities of adsorption isotherm models. The Ideal Adsorption Solution Theory (lAST) was found to adequately predict mixture sorption behaviour for all the materials considered.
