"Effective Diffusivities and Pore-Transport Characteristics of Washcoated Ceramic Monolith for Automotive Catalytic Converter" . "Using the chromatographic technique (carrier-gas: N2; tracer-gases: He, Ar) the effective diffusivity in single pellet-string columns (SPSC) packed with porous slab particles was studied. Dispersion due to extra column effects was eliminated via convolution of column responses for two lengths. The measurements were done for cordierite support particles and for cordierite support coated with alumina based washcoat particles. The effective diffusion coefficients for two tracer-carrier pairs were evaluated by fitting column response (chromatographic) peaks in time domain. Mean transport parameters were evaluated for both types of porous particles. Obtained mean transport pore radii are in reasonable agreement with pore size distribution from mercury porosimetry."@en .
