    KIT Scientific Publishing
    Details
    Publication Date: 2024-04-11
    Description: The present study addresses the combination of low-temperature Fischer-Tropsch synthesis (FTS) and hydrocarbon modification reactions (hydroprocessing) in one reactor. The objective of the present investigation was to study the influence of CO during hydroprocessing reactions of hydrocarbon model compounds on two different bifunctional catalysts. In addition, the influence of the catalyst-bed configuration for the combination FTS and hydrocarbon reactions was investigated.

    Partial oxidation of Raffinate II and other mixtures of n-Butane and n-Butenes to maleic anhydride in a fixed-bed reactor (2021)
    KIT Scientific Publishing
    Details
    Publication Date: 2024-04-11
    Description: The utilisation of the C4 streams of steamcrackers by converting raffinate II to maleic anhydride was studied. The oxidation reactions were investigated in a laboratory-scale fixed-bed reactor to determine reaction kinetics. The effects of pore diffusional resistance were investigated and explained. A two-dimensional pseudo-homogeneous reactor model was used for the simulation of a production-scale fixed-bed reactor. A flow scheme of the reactor section including a recycle was proposed.

    Dynamische Simulation der Mechanischen Flüssigkeitsabtrennung in Vollmantelzentrifugen (2021)
    KIT Scientific Publishing
    Details
    Publication Date: 2024-04-11
    Description: The aim of the present work is the mathematical modeling of solid bowl centrifuges for the dynamic simulation of separation processes in real time. The developed compartment model couples the residence time behavior with the material properties and thus allows a time and space-resolved simulation for solid bowl centrifuges. The profound insights into the separation process open up not only a better design, but also new fields of application such as the dynamic flowchart simulation.
