Abstract：

I would like to start this presentation by briefly introducing the zeolite-based adsorption/catalyst widely used in applications, for which the chemical engineering principles are mainly adopted. Specifically, I would like to present a zeolite-based internal combustion engine hydrocarbon trap and some useful chemical production from methane. In addition, I would like to talk about a method of upgrading carbon dioxide using zeolitic imidazolate framework-8 (ZIF-8) emerging as a new type of microporous material. After that, I will focus on manufacturing zeolite as a molecular sieving membrane. In particular, I would like to introduce the academic and industrial efforts for zeolite membrane-based applications. Finally, a recent attempt for the realization of membrane reactors will be addressed.

Bio of the Lecturer：

Jungkyu Choi received his BS degree in Chemical Engineering from Seoul National University (Republic of Korea) in 2003 and Ph.D. degree in Chemical Engineering from the University of Minnesota (USA) in 2008. After that, he spent almost three years at the University of California at Berkley (USA) as a postdoctoral research associate for zeolite membrane-based diffusion. He joined the Department of Chemical and Biological Engineering at Korea University as an assistant professor in 2011 and was promoted to an associate professor in 2015 and a full professor in 2020.He is currently leading the Inorganic Materials for Separation and Reaction (IMSR) Lab. He specializes in the synthesis and characterization of microporous materials (mainly zeolites) targeting for eventual uses at the industrial scale. Specifically, he is using the zeolites and other microporous materials (e.g., metal organic framework) as molecular sieving-based catalysts/supports, molecular filtering membrane constituents, and VOC-selective adsorbents. Recently, the combination of membrane and catalysis in the form of a membrane reactor was reported in an attempt to overcome equilibrium-limited dehydrogenation of a liquid organic hydrogen carrier (LOHC) at low temperatures. As of Jan. 11, 2026, he published approximately 132 papers and 120 domestic/international patents (both pending and registered).
