Abstract: The effectiveness of the air bio-purification process from vinyl acetate carried out in a pilot-scale trickle-bed bioreactor (TBB) was investigated in a continuous system for about 115 days. The experimental database, obtained for a wide range...

Abstract: Metal and ceramic solid foams were examined to determine axial dispersion for liquids (water and 45% glycerol solution) single phase flow; the results obtained for the packed bed of spheres were used for comparison. The influence of the liquid...

Abstract: Open cellularceramic foam with the Mn-Cu catalyst layered was investigated in the toluene combustion process. Foam morphology was studied using computed microtomography. The results proved satisfactory functioning of the foam supported catalyst,...

Abstract: Metallic foams appear as promising catalyst carriers for fast catalytic reactions. They combine many beneficial properties, like large specific surface area, high porosity and relatively low pressure drop. The foams can be regarded as an intermediate...

Abstract: In this paper, the morphological parameters and transport coefficients are studied for the reticulated vit-reous carbon (RVC) foams of pore density 30 and 80 PPI. SkySkan 1172 X-ray microtomograph was used to study the foam structure. Heat...

Abstract: The liquid holdup was determined experimentally for a trickle bed reactor with the solid foam filling. It was found that the commonly applied drainage time is too short to determine the liquid holdup properly. The liquid holdup was correlated...
