Multiphysics Simulation of a Packed Bed Reactor

A.E. Varela[1], and J.C. García[1]

[1]University of Carabobo, Valencia, Venezuela

Most reactor designs are based on pseudo homogeneous models. This paper studies the COMSOL simulation of a packed bed reactor using a 2-D heterogeneous model. The case considered was a packed reactor with spherical catalyst for oxidation of o-xylene in air to phthalic anhydride. Large ... Mehr lesen

A Computational Fluid Dynamics Study of Fluid Catalytic Cracking Cyclones

J. W. McTernan[1], I. Abu-Mahfouz[2]
[1]Buell Division of Fisher-Klosterman Inc., Lebanon, PA, USA
[2]Pennsylvania State University - Harrisburg, Middletown, PA, USA

Fluidized Catalytic Cracking (FCC) regenerators utilize a fluidized bed to facilitate catalyst regeneration. Cyclones are used to separate the catalyst from the gas stream and return the catalyst to the fluidized bed; as the gas progresses through the system for further processing. This ... Mehr lesen

Thermal Modeling of Chlorination Reactor

[1] Indira Gandhi Centre for Atomic Research, Kalpakkam, India

Chlorine reactor is used to dry molten LiCl-KCl eutectic salt before it is put to use in electrorefining operation. Molten salt electrorefining is a pyrochemical method of separation of heavy elements from spent metallic nuclear fuel. It is a high-temperature process which uses molten ... Mehr lesen

Model for Steam Reforming of Ethanol Using a Catalytic Wall Reactor

J. Torres[1], and D. Montane[2]
[1]Centre Huile Lourde Ouvert et Experimental (CHLOE), University of Pau, France
[2]Department of Chemical Engineering, Virgili University, Tarragona, Spain

Steam Reforming of Ethanol using a Catalytic Wall Reactor (CWR) was successfully studied using COMSOL Multiphysics. A mathematical model was used to describe the reactor performance in terms of the main variables and dimensionless groups. Simulations showed that at specified conditions ... Mehr lesen

Study of Electrochemically Generated Two-Phase Flows

J. Schillings [1], O. Doche [2], J. Deseure [1],
[1] LEPMI, Grenoble, France
[2] SIMAP, Grenoble, France

The dependency of electrochemical processes performances on mass transfer is well-known. Electrolyte flow in the vicinity of electrodes surface can enhance reactions due to increased mass transfer. This flow can be generated by the production of a gaseous phase, leading to a natural ... Mehr lesen

Advancements in Carbon Dioxide and Water Vapor Separations Using COMSOL Multiphysics®

J. Knox[1], R. Coker[1], R. Cummings[1], C. Gomez[1], G. Schunk[1]
[1]NASA, Marshall Space Flight Center, Huntsville, AL, USA

Some NASA efforts are focused on improving current systems that utilize fixed beds of sorbent pellets by evaluating structured sorbents, seeking more robust pelletized sorbents, and examining alternate bed configurations to improve system efficiency and reliability. For the bulk ... Mehr lesen

Some Commonly Neglected Issues Which Affect DEP Applications
