“…Foam supports are also commonly used catalysts supports because of their advantages, such as improved gas mixing and preheating, low pressure drop, high porosity, and superior heat and mass transfer coefficients. Nevertheless, foam supports are easily fragile and undergo significant thermal expansion when exposed to elevated temperature and serious thermal shock [21]. The pileup-pellet supports with discrete particles are preferred as alternatives to catalytic combustion at elevated temperatures because of the smaller size and stronger robustness of the particles compared with a rigid and continuous structure.…”

“…It can be explained that a reduction in pore size results in smaller passage for fluid permeation [7] . In terms of a strut size, one big advantage of cells encompassing big struts could be realized with sufficient strength of ceramic foam products [8] . …”

“…Hence, real industrial materials use more robust, but more amorphous, bidisperse structures. A commonly proposed alternative is oxide foam structures with porous walls (Faure et al 2011). However, for more amorphous structures, the aforementioned issues, with the conventional characterisation and modelling approach to assessing the impact of pore structure on mass transport, arise.…”

Determining structure-transport relationships is critical to optimising the activity and selectivity performance of porous pellets acting as heterogeneous catalysts for diffusion-limited reactions. For amorphous porous systems determining the impact of particular aspects of the void space on mass transport often requires complex characterization and modelling steps to deconvolve the specific influence of the feature in question. These characterization and modelling steps often have limited accuracy and precision. It is the purpose of this work to present a case-study demonstrating the use of a more direct experimental evaluation of the impact of pore network features on mass transport. The case study evaluated the efficacy of the macropores of a bidisperse porous foam structure on improving mass transport over a purely mesoporous system. The method presented involved extending the novel integrated gas sorption and mercury porosimetry method to include uptake kinetics. Results for the new method were compared with those obtained by the alternative NMR cryodiffusometry technique, and found to lead to similar conclusions. It was found that the experimentally-determined degree of influence of the foam macropores was in line with expectations from a simple resistance model for a disconnected macropore network.
