Fundamental Three Dimensional Modeling and Parameter Estimation of a Diesel Oxidation Catalyst for Heavy Duty Trucks

A. Holmqvist[1] and C.U.I. Odenbrand[1]

[1]Department of Chemical Engineering, Faculty of Engineering, LTH, Lund University, Lund, Sweden

Mathematical optimization can be used as a computational engine to generate the best solution for a given problem in a systematic and efficient way. In the context of monolithic converter systems, the parameter estimation problem (or inverse problem) is solved using Partial Differential ... Read More

Coupling Miscible Flow and Geochemistry for Carbon Dioxide Flooding into North Sea Chalk Reservoir

B. Niu[1], W. Yan[1], A.A. Shapiro[1], and E.H. Stenby[1]

[1]Department of Chemical and Biochemical Engineering, Technical University of Denmark, Kgs. Lyngby, Denmark

As an effective method to cope with green-house gas emission, and to enhance oil recovery, injection of carbon dioxide into oil reservoirs has obtained increasing attentions. The flooding process involves complex phase behavior among oil, brine and CO2, and geochemical reaction between ... Read More

Model Development and Implementation of a Membrane Shift Reactor

J. Völler[1], M. Follmann[1], C. Bayer[1], and T. Melin[1]

[1]AVT Chemical Process Engineering, RWTH Aachen University, Aachen, Germany

Low temperature fuel cells require hydrogen of high purity for electricity production to avoid catalyst poisoning. To purify hydrogenrich flue gases from hydrocarbon steam reforming membrane shift reactors with a metal membranes may be utilized. A model of a tubular membrane shift ... Read More

Finite Element Model of a Complex Glass Forming Process as a Tool for Control Optimization

F. Sawo[1] and T. Bernard[1]
[1]Fraunhofer Institute for Information and Data Processing IITB, Karlsruhe, Germany

This paper addresses the modeling of a complex glass forming process as an example of a complex, nonlinear distributed parameter system. The system is modeled by a fluid dynamics approach, which means that the forming is regarded as a fluid with free surfaces. Here, the coupling of the ... Read More

Two-Dimensional Modelling of a Non-Isothermal PrOx Reactor with Water Cooling for Fuel Cell Applications

H. Beyer[1], B. Schönbrod[1], C. Siegel[1], M. Steffen[1], and A. Heinzel[1][2]
[1]Zentrum für BrennstoffzellenTechnik GmbH, Duisburg, Germany
[2]Institut für Energie und Umweltverfahrenstechnik, University of Duisburg-Essen, Duisburg, Germany

This work treats of a preferential oxidation reactor, which is simulated by a two-dimensional axial symmetric model. The reactor serves as purification of hydrocarbon reformat and converts the CO mole fraction from up to 1 % in the feed gas down to a few ppm at the outlet to deliver a ... Read More
