Abstrakt: The analysis of the internal structure of RVC foams (Reticulated Vitreous Carbon) skeleton carried out by computed microtomography, did not allow to unambiguously determine to what extent their structure is discontinuous. Therefore, for more...

Abstract: The paper presents estimation of the viscous and inertial friction components for structured catalyst carriers such as: sinusoidal short-channel structure, knitted wire gauze, ring-rosette structure. Calculations based on the experimental results...

Abstract: In order to intensify transport processes, short-channel structural fillings of chemical reactors operating in the laminar flow regime should be characterized by a developing velocity profile in the subsequent sections. The paper discusses...

Abstract: The paper presents flow resistance of a new type of catalytic carriers - streamlined structures. They are short-channel structures (short monoliths) of various channel cross-sectional shape. The innovation of the design is channel wall similar...

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: Morphological parameters of the solid foams have been determined using computed microtomography, optical microscopy and helium pycnometry. For the first technique, impacts were studied of the voxel size and method of the image binarization...

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...

Abstract: Flow resistance and transport properties for air flow through metallic NiCr foam were experimentally studied. The foam was considered as a catalyst carrier in structured reactors. Heat transfer coefficients were determined by foam heating by...
