Mapping the Limitations of Breakthrough Analysis in Fixed-Bed Adsorption

J. Knox [1],
[1] NASA Marshall Space Flight Center, Huntsville, AL, USA

In a recent publication (Limitations of Breakthrough Curve Analysis in Fixed-Bed Adsorption, Ind. Eng. Chem. Res. 2016, 55, 4734-4748) the authors discussed the a priori prediction of the axial dispersion coefficient from available correlations versus obtaining it and also mass transfer ... Read More

Electrical and Bubbly Flow Modeling of a Molten Salt Electrolysis Cell

A. Oury [1], P. Namy [1], A. M. Martinez [2] , K. S. Olsen [2], A. Solheim [2] ,
[1] SIMTEC, Grenoble, France
[2] SINTEF Materials and Chemistry, Trondheim, Norway

A laboratory-scale electrolysis cell for the recovery of metals is simulated with COMSOL Multiphysics® software. Two models are implemented: an electrical model simulating the current density (reaction rate) distribution at the electrodes and a laminar bubbly flow model which solves for ... Read More

Transient CFD Investigation of a Photocatalytic Multi-tube Reactor

S. Denys [1], J. van Walsem [1], J. Roegiers [1], S. Lenaerts [1],
[1] University of Antwerp, Antwerp, Belgium

As in industrial countries, people spend most of their time indoors and the stringent heat-insulation measures in combination with deficient ventilation have a negative impact on indoor air quality, one approach for abating indoor air pollution is the integration or retrofitting of a ... Read More

Transient Diffusion Modeling of Methane Plume and Source Localization
