Determining Diffusivity by Breakthrough Measurements Using the Zero Length Column Method

Overview

Mass diffusivity into and among particles often dominates how adsorbents perform. Effective materials and processes for adsorption, catalysis, gas separation, and direct air capture can be developed more quickly and perform better when mass-transfer is well-understood.

Breakthrough is a valuable tool for measuring adsorption in dynamic conditions and can more closely mimic real world process conditions compared to static adsorption measurements. Monitoring data over time allows users to obtain valuable kinetic information during data collection. In this webinar the Zero Length Column (ZLC) method will be explored for breakthrough adsorption in order to determine the diffusivity of an adsorbate in an adsorbent. This webinar will first focus on the theory behind the ZLC method, then provide an example of how to measure and calculate the diffusivity from breakthrough data.
Who should attend:
– Researchers and processes engineers who need to optimize processes and materials for catalysis, gas separation and direct air capture
– Chemists and engineers developing high-performance nanoporous materials such as: zeolites, MOF’s, COF’s, membranes and activated carbons
– Users of breakthrough measurements who want to get more value from their data and deeper insight into their materials

Senior Application Scientist

Julian graduated from the University of Michigan with an undergraduate degree in Chemical Engineering. While attending the University of Michigan he conducted research under the guidance of Prof. Jinsang Kim in organic photovoltaics. He then went on to pursue his PhD at the Georgia Institute of Technology, working in Dr. Krista Walton's research group. His research focused on the adsorption of acid gases in metal-organic frameworks (MOFs). After completing his PhD, Julian joined Micromeritics in late 2020. He specializes in physisorption, separations, and porous materials.
