Leveraging Diffusion Kinetics to Reverse C3H8 C3H6 Adsorption in ZIF 8

In this presentation I discuss the kinetically driven separations of C3H6/C3H8 mixtures using ZIF-8. I investigate the influences of both crystal size and contact times on separations. I highlight the concept of optimum crystal size for kinetic separations. The experimental data on transient breakthroughs are reported in the paper Yang, L.; Liu, Y.; Zheng, F.; Shen, F.; Liu, B.; Krishna, R.; Zhang, Z.; Yang, Q.; Ren, Q.; Bao, Z. Leveraging Diffusion Kinetics to Reverse Propane/Propylene Adsorption in Zeolitic Imidazolate Framework‑8. ACS Nano 2024, 18, 3614-3626. https://doi.org/10.1021/acsnano.3c11385. The set of experiments are in good agreement with transient breakthrough simulations using the Maxwell-Stefan diffusion formulation taking due account of thermodynamic coupling. The simulation details are to be found in my papers Krishna, R. Fundamental Insights into Intra-Crystalline Diffusional Influences on Mixture Separations in Fixed Bed Adsorbers.
