(383w) Synthesis of Cucl-Impregnated Zeolite-Based Adsorbent and Its Application to CO Separation

Carbon monoxide (CO), a toxic gas, is released from various industrial activities like steel production and partial oxidation processes. Given its potential utility in synthesizing high-value chemical compounds, extensive research is underway to economically separate unreacted CO after reaction. Adsorption-based separation processes offer advantages including ease of regeneration and low energy consumption. However, zeolite, a widely used adsorbent, while competitively priced, exhibits limited selectivity towards CO. To address this limitation, CuCl(I) is proposed for its affinity towards CO via π-complexation, potentially improving CO selectivity and adsorption performance. Traditional solid-state synthesis methods often result in uneven dispersion of cuprous ions onto zeolite surfaces and pores, necessitating a wet impregnation method to enhance CuCl(I) dispersion onto type Y zeolite. This study examines changes in adsorption performance and adsorbent characteristics depending on synthesis methods. Furthermore, optimal mass ratios of CuCl(I) to type Y zeolite are investigated to determine their impact on CO adsorption performance.
