“…A well-known example of PI through structuring of the apparatus is the implementation of structured packings in continuous distillation columns [23]. These packings are composed of vertical crimped sheets, increasing the packing porosity from 40% to more than 80% in comparison to a random particle packing in similar geometric surface areas [24].…”

“…By stapling of the foils guiding the reactants and the heat transfer fluids (a principle known from plate heat exchangers), reactors with excellent temperature control can be built, which may open novel process windows for so-called flow chemistry devices [28,29]. Beginning in 2003, open-celled foam structures have become more and more the focus of research due to their extremely high porosity and surface area [24,30]. Furthermore, such structures also provoke a radial transfer of matter which is not present in monolithic packings, making them less sensitive to initial liquid distribution.…”

Modeling of three‐phase continuously operating open‐cell foam catalyst packings: Sugar hydrogenation to sugar alcohols

et al. 2022

An advanced comprehensive and transient multiphase model for a trickle bed reactor with solid foam packings was developed. A new simulation model for isothermal three-phase (gas-liquid-solid) catalytic tubular reactor models was presented where axial, radial, and catalyst layer effects were included. The unique feature of this model is that the material balances include most of the individual terms (i.e., internal diffusion, gas-liquid, and liquid solid mass transfer, kinetics) for solid foam packing which is seldom done. Hydrogenation of arabinose and galactose mixture on a ruthenium catalyst supported by carbon-coated aluminum foams was applied as a fundamentally and industrially relevant case study. Parameter estimations allowed to obtain reliable and significant parameters. The effect of the kinetic parameters and the operation conditions on the arabinose and galactose conversions was studied in detail by sensitivity analysis. The model described is applicable for other three-phase continuous catalytic reactors with solid foam packings.
