Analysis of single and multi-stage membrane reactors for the oxidation of short-chain alkanes—Simulation study and pilot scale experiments

Analysis of a fluidized bed membrane reactor for butane partial oxidation to maleic anhydride: 2D modelling

“…The selection of a 2D model, more difficult to solve than 1D models, is justified by the presence of important temperature and concentration gradients in the radial coordinate, due to the reduced rates of the heat and mass transport through the reactor wall and the membrane. This model has been successfully used in the simulation of the oxidation of short-chain alkanes (Hamel et al, 2008).…”

Three-dimensional CFD simulation of industrial Claus reactors

“…COMSOL has been successfully used before to model packed-bed reactors(Karim, Bravo, and Datye 2005;Bey and Eigenberger 1997;Hamel et al 2008;Moustafa, Abou-Elreesh, and Fateen 2007).Three Multiphysics models were used in the simulation: Free and porous media flow model, transport of diluted species for six species and heat transfer model. Despite the simple geometry of the problem, the numerical solution did not easily converge due to the sensitivity of the model to the effect of k 0 found in the KE1 and KE2 kinetic equations.…”

Analysis of Membrane Reactors for Integrated Coupling of Oxidative and Thermal Dehydrogenation of Propane

“…For that reason, initially an inert packed bed membrane reactor (PBMR) for a distributed dosing and lowering O 2 on VO x is considered ( Fig. 2b) [16,26,27]. c) Furthermore, the ODH has been performed in a packed bed catalytic membrane reactor (PBCMR).…”

“…The impregnated catalyst was washed, dried and calcinated. The vanadium content of the catalyst was 1.4 % and its specific area 158 m 2 g -1 (BET) [26,27,29]. A chromium catalyst (configuration c) + d)) was also prepared via impregnation of g-Al 2 O 3 support (1.8 mm, 200 m 2 g -1 ) with chromium nitrate nonahydrate in water and is characterized by a chromium content of 5.8 % and a specific area of 178 m 2 g -1 .…”
