A Multiscale 3D Packed Bed Reactor

Radial flow fixed bed reactors are used to carry out large-scale catalytic reactions. Simulation of said reactors allows observation of effects of varying conditions in the reactor. Using a 2D previously developed axisymmetric model in COMSOL, creation of a more comprehensive model of the reactor was attempted.

 · In this study, a detailed three-dimensional modeling of a channel-type reactor with a plate heat exchanger for cobalt-based FTS was conducted using COMSOL Multiphysics 4.0a (COMSOL, Inc.) for the purpose of providing useful information on the design of channel structure and the determination of operating conditions in the case of numbering-up.  · Palladium-based catalytic membrane reactors (CMRs) effectively remove H 2 to induce higher conversions in methane steam reforming (MSR) and water-gas-shift reactions (WGS). Within such a context, this work evaluates the technical performance of a novel CMR, which utilizes two catalysts in series, rather than one.

Modeling Flow through a Fixed Bed Packed Reactor Nicole Reed EGEE 520 Spring 2008 Instructor: Dr. Derek Elsworth Abstract A fixed-bed flow reactor packed with activated carbon has been modeled using COMSOL Multiphysics. Fixed beds are used to test the performance of adsorbents for sulfur removal from liquid COMSOL Multiphysics was used to model methane steam reforming (MSR) and glycerol steam reforming (GSR) in a fixed bed reactor of tube-to-particle diameter ratio N = 5.96. The calculations were made using a steady- state 1D heterogeneous model, made up of an effective medium reactor tube model coupled to a single spherical pellet model for the source term at each point of the tube.
