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 problems related to the utilization of low-concentration methane emitted with the ventilation air from coal mines into the atmosphere are discussed. A short review of the methods of such utilization proposed in the literature was made,...

Abstract: The issue of utilization of hydrogen sulfide and the reduction of its emissions is a key issue and results from its extraordinary toxicity to both humans and the environment. Due to the strong corrosive properties of H2S, its removal is necessary...

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: 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: 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...
