Metal foams are considered as promising catalyst carriers due to their high porosity, large specific surface area, and satisfactory thermal mechanical stability. The study presents heat transfer pressure drop experiments performed for seven of different pore densities made from diverse metals. Mass characteristics derived using the Chilton–Colburn analogy. It was found that display much more intense heat/mass than a monolith, comparable packed bed. Next, foams’ efficiencies have been...
In this study, we present a modulated synthesis nanocrystalline defective UiO-66 metal-organic framework as potential chloroquine diphosphate (CQ) delivery system. Increasing the concentration of hydrochloric acid during resulted in considerable increase pore volume, which enhanced CQ loading CQ@UiO-66 composites. Drug release tests for composites have confirmed prolonged comparison with pure CQ. vivo on Danio reiro model organism revealed that released from 25% showed lower toxicity and...
A significant problem in hard coal mining is the utilisation of ventilation air methane (VAM). Two basic combustion methods, thermal (homogeneous) and catalytic oxidation, are analysed detail this paper. Both processes compared based on numerical simulations, applying reaction kinetics developed previous works, assuming a few typical monolithic reactor packings. The reactor’s mathematical model kinetic equations presented. results presented graphically as temperature reactant concentration...
The application of methane as a fuel in the automotive industry shows an increasing tendency, but its release into atmosphere is detrimental due to very high greenhouse effect. For this reason, new solutions for cleaning systems exhaust gas from engines are demand. This study focuses on thorough characterisation active centres, structure–activity relationships, and reaction steps palladium ceria supported catalysts different loading, using situ FTIR method with surface probe molecules....
The paper present a test result of the quality timing belt pulley. pulleys have significant impact on coupling with This is connected problem accuracy movement and displacement. majority transport realized use conveyor belts. Parallel conveyors, manipulators, electric actuators motion, transmission depends gears, specially Measurements these show number errors, affecting kinematics dynamics whole system-transport. It also one most important parameters durability belt. wheels chosen...
Innovative structured catalyst supports, like solid foams, wire gauzes, and short-channel structures, are considered in methane catalytic combustion. For comparison, classical supports such as packed beds monoliths also taken into account. Moreover, two catalysts, displaying "fast" "slow" kinetics, examined. The performance efficiency criterion is applied to account for a balance between the process conversion, mass transfer, flow resistance. Another "technological" approach compares reactor...
X-ray based computed microtomography is a non-destructive, well established tool for three-dimensional characterization of open-cell metallic foams. Macroscopic physical and chemical properties these materials stay in close relation to their micro-structure parameters. The purpose the paper present two types thresholding methods so-called global local evaluating structural parameters metal foams on data. Two different were chosen: automatic Otsu (global) adaptive (mean minimal maximal grey...
The actual state of the macrogeometry surfaces mating elements, particularly form deviations, has a direct influence on constructional features and functionality connections which are applied in mechanical engineering. authors made an attempt to assess radial cross-section deviations their compilations occurrence variable values local stresses displacements caused by limited contact zone connection. problems represented example numerical simulation between rigid non-deformable hub shaft with...
