Abstract

"Transition to a clean, renewable energy future requires departure from thermally driven separation processes. In that regard, development of new materials that exhibit high adsorption capacity and selectivity, fast kinetics, and long-term durability under multicomponent conditions is becoming attractive for the applications in clean energy. Moreover, novel sorbents and separation systems that can store gases at normal conditions offer a promising approach for stationary or onboard gas storage. Due to the limitations on the surface area and biding energy restrict commercial materials effectiveness as a potential adsorption and storage material. There is significant interest in the properties of hybrid materials for their potential to improve gas capacity and selectivity.

The first phase of this research focuses primarily on developing novel hybrid materials comprised of MOF and zeolite with core-shell structure for H2 purification to achieve large adsorption capacity, high selectivity, and fast kinetics under multicomponent. In addition, the kinetics of H2 purification over high-surface area Activated carbon under pressure swing adsorption conditions were systematically investigated. In the second phase of this research, CH4 storage performances of hybrid nanocomposite adsorbents comprised of MOF and graphene oxide, and highly porous aerogel-derived carbon adsorbents were investigated. The potential of these adsorbents for use in adsorbed natural gas tanks was thereafter demonstrated. The findings of this dissertation highlight the importance of synergistic effects of constituents in hybrid adsorbents in promoting adsorption/storage efficiencies, while fully assessing their performance under more realistic conditions"--Abstract, p. iv
