  1. Investigations on the Low Temperature Methanation with Pulse Reaction of CO

    Jens Friedland, Thomas Turek and Robert Güttel

    Version of Record online: 19 AUG 2016 | DOI: 10.1002/cite.201600056

    Transient experiments usually provide huge data sets depending on the sampling frequency of the analytics. The analysis and condensation of data is challenging. The application of moment analysis for a pulse-type experiment with chemical reaction is shown to allow data reduction while maintaining meaningful results for interpretation.

  2. 1D Model for Coupled Simulation of Steam Cracker Convection Section with Improved Evaporation Model

    A 1D model is developed to simulate a complete steam cracker convection section enabling fast simulations. Hence, optimization and design of the convection section can be performed. The accuracy of the evaporation model is improved by implementing a mechanistic evaporation model, taking into account the different flow regimes.

  3. Katalytische Methanisierung von Kohlenstoffdioxid

    Power-to-Methane ist eine attraktive Option zur Speicherung der Stromüberschüsse aus fluktuierenden, erneuerbaren Energiequellen. Das Konzept gewann in den letzten Jahren großes Interesse. Ein wesentlicher Teil der Prozesskette des Power-to-Methane ist die katalytische Methanisierung von CO2. Wesentliche Fundamente und Verfahren werden in diesem Beitrag vorgestellt.

  4. Thermodynamics of Multicomponent Liquid Chromatography

    Dorota Antos and Wojciech Piątkowski

    Version of Record online: 12 AUG 2016 | DOI: 10.1002/cite.201600048

    Thermodynamic models of multicomponent liquid chromatography are presented. The competitive and synergistic effects that accompany chromatographic elution are illustrated and described within thermodynamic framework. The effect of the mobile phase modifier on the retention pattern of the chromatographed species is discussed.

  5. Impact of Thermo-Physical Data on the Modeling of High-Pressure Polymerizations

    Kristina Maria Pflug and Markus Busch

    Version of Record online: 12 AUG 2016 | DOI: 10.1002/cite.201600082

    The influence of mixture viscosity and heat capacity on the process modeling of high-pressure polymerization of ethene in tubular reactors is evaluated. Special attention is paid to the heat balance, the conversion and the properties of the resulting LDPE mainly depicted by the molecular weight distribution.
