Adsorption of amino acids on MFI-type zeolite: DFT calculations and experimental results
Adsorption is a common unit operation in separation and purification of biotechnological products where chromatography steps can make up more than half the amount of the total purification costs [1]. The molecular mechanisms of adsorption are still not understood in detail. Further understanding of interactions between adsorbent surfaces and adsorptives could help to facilitate process design i...
متن کاملTheoretical and experimental study of the pH-dependent interaction of amino acids and MFI-type zeolite
The separation and purification of peptides and proteins using chromatography can make up more than half the amount of the total purification costs of a biotechnological process [1]. The development of cost-efficient processes still suffers from the lack of understanding on a molecular level of adsorption mechanisms of biomolecules on materials surfaces. To explore the power of computer science...
متن کاملPhysical adsorption analysis of intact supported MFI zeolite membranes.
We compare the adsorption properties of intact supported silicalite membranes with those of silicalite powder and of alumina supports using nitrogen and argon as adsorbates at 77 K. We disentangle contributions from the membrane and support and find that the support contributes significantly to the total quantity adsorbed due to its relative thickness. The micropore-filling regions of the adsor...
متن کاملMicro-Imaging by Interference Microscopy: A Case Study of Orientation-Dependent Guest Diffusion in MFI-Type Zeolite Host Crystals
Because of the small particle size, orientation-dependent diffusion measurements in microporous materials remains a challenging task. We highlight here the potential of micro-imaging by interference microscopy in a case study with MFI-type crystals in which, although with different accuracies, transient concentration profiles in all three directions can be observed. The measurements, which were...
متن کاملGas Diffusion in Polycrystalline MFI-type Zeolite Membranes
1. Introduction 1. Introduction Information on mass transport in polycrystalline zeolite membranes is necessary for a theoretical estimation of the membrane performances. Zeolite membranes are usually prepared as thin layer of an assembly of small zeolite crystals including many intercrystalline regions. Thus, the intercrystal region would influence their individual diffusion properties, which ...
