Influence of liquid composition on diffusive mass transfer in the lubricating film of Taylor flow—A study related to the hydrogenation of nitrobenzene

Sunflower Hydrogenation in Taylor Flow Conditions: Experiments and Computational Fluid Dynamics Modeling Using a Moving Mesh Approach

“…As a consequence, innovative three-phase monolith type reactors have grown in interest in recent years, due to the particular features of the Taylor flow where bubbles are separated by liquid slugs. − Such a flow structure indeed provides plug flow behavior and a low pressure drop, while enhancing gas–liquid mass transfer due to the presence of recirculation vortices in the liquid slugs and a thin lubrication film between the bubbles and the wall…”

“…In addition, the flow regime is usually laminar in the liquid slug, with a Reynolds number based on the bubble velocity, Re = ρ L U B d c /μ L , less than 1000, for instance, 0.01 < Ca < 0.1 and Re < 200 in Woo and co-workers , and Ca < 0.01 and Re < 1000 in Durán Martínez…”

Rice husk-SiO2 supported bimetallic Fe–Ni nanoparticles: as a new, powerful magnetic nanocomposite for the aqueous reduction of nitro compounds to amines

“…14,15 Besides, nickel catalysis has made tremendous advances in organic synthesis, especially the synthesis of heterocycle compounds, which have been widely used among a variety of pharmaceutical compounds due to their relative insensitivity to air, low toxicity and price. [16][17][18][19][20] The design and preparation of green catalysts have attracted much attention in both academic area and pharmaceutical industry. 21 For this mean, heterogenization of the catalysts to solid supports is one of the interesting choices to prevent wasting the catalyst.…”
