In the present work, the performance of a tubular electrochemical reactor operated with three different inlets (central, lateral and tangential) was evaluated. Fluid flow simulations through the electrochemical reactor were performed using computational fluid dynamics (CFD). The steady state fluid flow was simulated to visualize the velocity field behavior along the reactor for each different i...

Organic solid wastes were treated in various types of methanogenic bioelectrochemical reactors, equipped with an external electrochemical system to control electron flow and improve microbial activity. At a high organic loading rate, cathodic bioelectrochemical reactors demonstrated greater decomposition of artificial garbage slurry and higher methane production than both anodic bioelectrochemi...

Two membrane electrochemical reactors (MER) were designed and applied to HLADH-catalysed reduction of cyclohexanone to cyclohexanol. The regeneration of the cofactor NADH was ensured electrochemically, using either methyl viologen or a rhodium complex as electrochemical mediator. A semi-permeable membrane (dialysis or ultra-filtration) was integrated in the filter-press electrochemical reactor ...

A model is presented for a parallel plate electrochemical reactor which has electrodes that are the same size and are close together. That is, the distance between the electrodes (S) is much smaller than the length (L) or width (W) of the electrodes. Consideration of the material balance equations in light of this small aspect ratio (S/L) condit ion leads to predict ions of derived quanti t ies...

This paper presents an overview of the design of electrochemical processing equipment for semiconductor and related microelectronic manufacturing as well as a review of publications that are applicable to electrochemical wafer process equipment. We discuss several types of electrochemical processes applicable to wafer processing and the considerations that go into automated equipment for these ...

Transport processes in an upright, concentric, annular, electrochemical reactor filled with RedOx electrolyte solution are studied experimentally and theoretically. The electrodes form the two vertical surfaces of the reactor. The theoretical calculations consist of the solution of the Navier-Stokes and the Nernst-Planck equations accounting for species' diffusion, migration, convection, and el...

the performance of a plug flow electrocoagulation reactor for the treatment of cattle abattoir(slaughterhouse) wastewater was investigated. a cylindrical iron reactor was operated as a cathode at arecycling batch mode while three iron rods located at the center of the reactor were used as an anode. theeffects of different parameters, including the current density, the supporting electrolyte dos...

An electrochemically driven, nickel-catalyzed reductive coupling of N-hydroxyphthalimide esters with aryl halides is reported. The reaction proceeds under mild conditions in a divided electrochemical cell and employs a tertiary amine as the reductant. This decarboxylative C(sp3)-C(sp2) bond-forming transformation exhibits excellent substrate generality and functional group compatibility. An ope...
