Modeling of a catalytic fluidized bed reactor via coupled CFD-DEM with MGM : from intra-particle scale to reactor scale Ghent University
The Computational Fluid Dynamics -Discrete Element Method (CFD-DEM) method is extended by coupling with the multi-grain model (MGM) to include particle growth due to a gas-solid reaction, as well as intra-and inter-particle phenomena such as heat and mass transfer, and reaction, next to the inter-particle and fluid-particle interactions in the reactor. This comprehensive model treats each particle individually and accounts for changes in ...
Kinetic study of thermocatalytic decomposition of methane over nickel supported catalyst in a fluidized bed reactor Ghent University
ThermoCatalytic Decomposition of methane (TCD) offers an interesting route to convert natural gas into hydrogen and functional carbon. In this study the reaction kinetics of TCD is studied for a nickel supported catalyst using a special fluidized bed reactor. The effect of operating conditions such as temperature, concentrations of methane and hydrogen and space velocity (SV) was studied on a commercial nickel catalyst on a silica support. The ...

Invariant expressions for linear complex mechanisms : generalization for polar two-step sub-mechanisms Ghent University
Stabilization time modeling for hydroprocessing : identification of the dominant factors Ghent University
Probing the performance of a Ni–Ca–Ce dual-functional material for integrated CO2 capture and utilization from a synthetic flue gas approximating industrial composition Ghent University
Confining CO2 emissions and accelerating toward a circular carbon economy demand process intensification strategies. This work evaluates integrated CO2 capture and catalytic conversion over a solid dual-functional material (DFM) in the presence of H2O and O-2, approximating industrial compositions in a laboratory-scale fixed-bed reactor. CO2 from flue gas and its isothermal utilization with H-2 are temporally separated by applying chemical ...
Amidoxime-functionalized covalent organic framework as simultaneous luminescent sensor and adsorbent for organic arsenic from water Ghent University
Organoarsenic compounds are widely used as feed additives in the poultry industry. However, the release of organoarsenic-containing wastewater can cause serious poisoning to the ecosystem. For this reason, detection and adsorption of organic arsenic from wastewater is crucial but also very challenging. Here, the use of covalent organic frameworks (COFs) as fluorescence sensors and adsorbents for the detection and adsorption of organic arsenic ...
