"This research focuses on the In-Situ CO2 capture and utilization in the oxidative dehydrogenation of ethane (ODHE) for ethylene production, and a subsequent ethylene purification through adsorptive separation process. In particular, several dual-function materials (DFMs) were developed, formulated into 3D-structure, and investigated for ODHE reaction to ethylene under various process conditions using CO2 as a mild oxidant. The DFMs materials were consisted of CaO and metal oxides (e.g., Cr2O3 and V2O5) supporting H-ZSM-5. The results indicated that higher cell densities lead to better performance due to kinetic enhancement, and the optimum configuration is separate stacking of the adsorbent and catalyst phases.

In the second part of the research, an induction swing adsorption process was designed, and a series of novel magnetic-responsive sorbents were developed for ethylene purification. The results indicated that both sets of sorbents (Fex/MOF-74 and Fex/13X) had high ethylene adsorption capacity, selectivity, and regeneration when exposed to an electromagnetic field. With a 20% Fe3O4 /13X, the highest energy absorption was observed with the greatest ethylene desorption rate of 0.69 mmol/g. min. Interestingly, using induction heating, the cooling rate is 71% faster than the conventional heating method. Furthermore, the selectivity of C2H4/C2H6 was constant at 4.10 even in the presence of impurity gases (e.g., CH4, H2) as in ternary and multicomponent gas mixtures. Overall, novel DFMs formulations for CO2 capture-conversion processes, in particular for the production of light olefins, are developed, along with magnetic sorbents that facilitate the capture and purification of olefins from paraffins via induction heating"--Abstract, p. iv
