  1. Evaporation and Decomposition Behavior of Pure and Supported Ionic Liquids under Thermal Stress

    Florian Heym, Wolfgang Korth, Johannes Thiessen, Christoph Kern and Andreas Jess

    Article first published online: 27 MAR 2015 | DOI: 10.1002/cite.201400139

    The behavior of pure and supported ionic liquids (ILs) under thermal stress was investigated. Based on these results general strategies to determine the volatility and stability of pure and supported ILs and criteria for the maximum operation temperature with regard to decomposition and evaporation are presented.

  2. Kinetic Investigation Exploiting Local Parameter Subset Selection: Isomerization of 1-Decene using a Rh-Biphephos Catalyst

    Andreas Jörke, Susann Triemer, Andreas Seidel-Morgenstern and Christof Hamel

    Article first published online: 27 MAR 2015 | DOI: 10.1002/cite.201400148

    Kinetic investigations regarding the double bond isomerization of 1-decene were performed to parameterize a kinetic model based on catalytic mechanisms. A method based on parameter sensitivities was extended and exploited to determine the subset of sensitive and unique kinetic parameters to increase their reliability. From this, conclusions regarding the reaction mechanism can be drawn.

  3. Simulation of One-Stage Dimethyl Ether Synthesis over a Core-Shell Catalyst

    Simulation of diffusion and reaction in catalysts and reactors is a useful tool in model-based catalyst preparation and reactor optimization. In this contribution, a 1D heterogeneous model is developed to simulate one-stage DME synthesis from synthesis gas in a core-shell catalyst, which has a zeolitic H-ZSM-5 shell layer to improve the selectivity to DME.

    Zur Verringerung der Treibhausgasemissionen wird eine Substitution der Erdöl-basierten Flüssigtreibstoffe durch nachhaltige, CO2-neutrale Biotreibstoffe angestrebt. Die thermo-chemische Umwandlung von Biomasse durch Flüssigphasenpyrolyse und die danach folgende Pyrolyseöl-Hydrodeoxygenierung und Pyrolysekohle-Verflüssigung wird beschrieben.
