Washcoated catalysts on honeycomb substrates are widely used as automotive catalysts, and it is well known that their catalytic performance is limited by gas transport resistance. In order to reduce the gas transport resistance, understanding the relationship between gas transport and pore properties is essential. Since a washcoat layer consists of porous metal oxide particles (e.g., Al2O3), the washcoat layer has two types of pores: primary pores, which are located inside the porous metal… Expand

Characterization of secondary pores in washcoat layers and their effect on effective gas transport properties
Abstract It is well known that the performance of monolithic catalysts is limited by gas transport resistance in the washcoat layer. Gases are transported via two types of pores within the washcoat… Expand
Analysis of the Gas Diffusivity in the Simulated Washcoat Layer Based on Mean Transport Pore Model and Mean Molecular Speed
The pore structure of a simulated washcoat layer was evaluated using the Mean Transport Pore Model (MTPM). The MTPM provides the mean diffusive pore radius (rm) of a simulated washcoat layer from the… Expand
Strategy for predicting effective transport properties of complex porous structures
TLDR
The reconstruction of porous alumina catalyst carrier with bimodal pore size distribution is demonstrated and it is shown that the contribution of nano-pores towards the total diffusion flux is significant and cannot be neglected, but it is reasonable to neglect the contribution to the sample permeability.
