“…Another method proposed in the literature to provide the necessary heat to the catalytic reactor is to couple the ammonia decomposition reaction with an exothermic reaction. This is the case proposed by Chen et al, 98 who designed a microreactor where channels with a platinum catalyst were used for the combustion of a methane−air mixture. The gases are alternated with other channels for the decomposition of ammonia in the presence of ruthenium, obtaining a compact reactor of reduced size.…”

Because of the problems associated with the generation and storage of hydrogen in portable applications, the use of ammonia has been proposed for on-site production of hydrogen through ammonia decomposition. First, an analysis of the existing systems for ammonia decomposition and the challenges for this technology are presented. Then, the state of the art of the catalysts used to date for ammonia decomposition is described considering the catalysts composed of noble and non-noble metals and their combinations, as well as novel materials such as alkali metal amides and imides. The effect of the supports and promoters used is analyzed in detail, and the catalytic activity obtained is compared. An analysis of the kinetics of the reaction obtained with different catalysts is also presented and discussed, including the reaction mechanism, the determining step of the reaction, and the apparent activation energy. Finally, the structured reactors used to date for the decomposition reaction of ammonia are explored, as well as the possibilities offered by catalytic membrane reactors, which allow the on-site simultaneous production and separation of hydrogen.

“…The main advantages of CFD modeling of flow dynamics in the packed bed are the low cost of the investigation in comparison with the experiments, as well as an evident visualization of the results. The different commercial and open‐source codes are applied for CFD simulation of flow in the packed bed, for example, ANSYS Fluent, Comsol Multiphysics, Autodesk Simulation CFD, OpenFOAM (open source), and so on.…”

Numerical simulations and experiments have been carried out to explore the effect of particle shapes on the pressure drop and the loss factor in a packed fixed bed filled with a porous catalyst. The packed bed is presented by the Ni‐Al2O3 catalyst of the different shapes. The commercial program ANSYS Fluent is used for the analysis; more than 20 mln cells are used for computational fluid dynamics (CFD) modeling. The catalyst particles were set as a porous medium with the viscous resistance coefficients and the inertial resistance coefficients. The comparison of the pressure drops between the experimental and simulation results show a good correlation with the divergence of results <8%. To determine the effect of the porosity properties of the medium on the numerical results, two cases of CFD modeling were realized (with taking into account the porous medium properties and without it). The discrepancy between results increases with an increasing gas flow rate.
