Modeling and Predicting Adsorption processes in Porous Media
Seminar recording
Innovative materials and optimized structures are crucial for improving separation processes and making purification and filtration systems more efficient. The three-dimensional microstructure of porous materials holds particularly great potential. Adsorbents such as activated carbon, zeolites, foams, or functionalized composites possess complex pore networks that significantly influence adsorption capacity, selectivity, and transport behavior. However, many of these properties at the pore level are difficult or impossible to determine directly through experimentation.
Using digital material models and simulations, microstructure-dependent adsorption properties can be analyzed and predicted based on detailed 3D models. This allows for a better understanding of structure-property relationships, targeted optimization of material performance, and the identification of limiting factors such as diffusion constraints or restricted pore accessibility. Digital simulation environments thus provide valuable insights into microstructure and transport phenomena—and support the development of efficient and sustainable adsorption materials without the need for prototypes.
In this seminar you will learn step-by-step:
- Filter Modeling: Digitally create an interior air filter with multiple fiber layers and an adsorbent activated carbon layer.
- Fundamentals of Adsorption in GeoDict: Learn the key prerequisites for running adsorption simulations with GeoDict.
- Simulation Setup: Configure an adsorption simulation and prepare it for analysis.
- Understanding Structure-Property Relationships: Evaluate the influence of microstructure on capacity, transport behavior, and accessibility.
- Interpreting Results: Evaluate relevant simulation results and derive insights for material optimization.
- Leveraging Digital Development: Targetedly improve adsorption materials and make development processes more efficient.
