Abstract:

The feasibility of electrolytic removal of tetrachloromethane from industrial effluents has been investigated. A new method based on the electrochemical reductive dechlorination of CCl4 yielding chloroform is described. The main goal was not only to remove CCl4 but also to utilize the process for obtaining chloroform, which can be industrially reused. GC-MS analysis of the electrolysed samples showed that chloroform is the only product. Voltammetric experiments were made in order to select experimental conditions of the electrolysis. Using energetic and economic criteria, ethanol-water (1 : 4)

Hydrogen production from water electrolysis is one of the most promising approaches for the production of green H2, a fundamental asset for the decarbonization of the energy cycle and industrial processes.

The most mature water electrolysis technology is alkaline electrolysis, where an aqueous solution of KOH is used as the electrolyte. While this technology has been used for decades, there is still a lot of potential to improve the performance of these devices. Much research is focused on the optimisation of the electrodes containing novel catalyst materials that lower the activation energy barrier of the electrolysis process. However, one of the issues described by Ehlers et al.1 is that the current academic electrolysis research is done under conditions that are far from practical (e.g. at lo

Background – The first experimental activities at Institute for Energy Technology (IFE) on high-pressure (16 bar) proton exchange membrane (PEM water) electrolysis systems based on variable renewable power was performed in 2004-2008 [1]. In 2016 IFE started to develop a national research infrastructure for testing of small-scale (33 kW) pressurized (up to 200 bar) low temperature PEM water electrolyser stacks [2].

Abstract:

There is a significant push to reduce carbon dioxide (CO2) emissions and develop low-cost fuels from renewable sources to replace fossil fuels in applications such as energy production. As a result, CO2 conversion has gained widespread attention as it can reduce the accumulation of CO2 in the atmosphere and produce fuels and valuable industrial chemicals, including carbon monoxide, alcohols, and hydrocarbons. At the same time, finding ways to store energy in batteries or energy carriers such as hydrogen (H2) is essential. Water electrolysis is a powerful technology for producing high-purity H2

Abstract:

A high-precision continuous dressing technology, namely ultrasound-aided electrolytic in-process dressing method, was proposed in this paper, aiming at overcoming the difficulty in continuous dressing for fine diamond wheel during the super mirror processing, such as optics and aeronautics. Firstly, the influence of high-frequency ultrasonic vibration on electrolysis was analyzed on the basis of the mechanism of electrolysis.

Abstract:

Due to its prevalence in nature and its particular properties, silicon is one of the most popular materials in various industries. Currently, metallurgical silicon is obtained by carbothermal reduction of quartz, which is then subjected to hydrochlorination and multiple chlorination in order to obtain solar silicon. This mini-review provides a brief analysis of alternative methods for obtaining silicon by electrolysis of molten salts. The review covers factors determining the choice of composition of molten salts, typical silicon precipitates obtained by electrolysis of molten salts, assessmen

Abstract:

This study proposes a multitype electrolytic collaborative hydrogen production model for optimizing the capacity configuration of renewable energy off grid hydrogen production systems. The electrolytic hydrogen production process utilizes the synergistic electrolysis of an alkaline electrolyzer (AEL) and proton exchange membrane electrolyzer (PEMEL), fully leveraging the advantages of the low cost of the AEL and strong regulation characteristics of the PEMEL. For the convenience of the optimization solution, the article constructs a mixed linear optimization model that considers the constraint

Abstract:

In the future, hydrogen (H2) will play a significant role in the sustainable supply of energy and raw materials to various sectors. Therefore, the electrolysis of water required for industrial-scale H2 production represents a key component in the generation of renewable electricity. Within the scope of fundamental research work on cell components for polymer electrolyte membrane (PEM) electrolyzers and application-oriented living labs, an MW electrolysis system was used to further improve industrial-scale electrolysis technology in terms of its basic structure and systems-related integration.

Abstract:

We developed an innovative technology of electrolysis-cavitation water purification and water treatment in pools. This method belongs to the group of physical water purification methods and its advantage is the absence of the need for costly chemical disinfectants and a degree of water purification from biological and organic pollutants of up to 97–98 %. A typical electrolytic water treatment process, based on electrolysis disengagement of sodium chloride with the formation of reactive sodium hypochlorite, is complemented by the operation of water cavitation disinfection from organic and

Abstract:

In the Hall-Héroult process for extracting aluminum, the evolution and dynamics of anodic bubbles have a significant influence on the efficiency of the overall electrolysis process. In this study, the behavior of the bubbles beneath the carbon anode in cryolite-alumina molten salt was studied for the first time using a laboratory-scale transparent electrolysis cell to view the anode from the bottom. The bubble dynamics and the relevant characteristic parameters of bubbles were obtained using video cameras and image processing. It was found that the bubbles were observed to preferentially gener

Herein, a new milling method via an electrochemical reaction is proposed to realize the high-speed machining of sintered carbide. In this method, cobalt (Co) on the surface of the sintered carbide is eluted via an electrochemical reaction, and the sintered carbide weakened by the elution of Co is scraped off with an insulating cutting edge. Results show that the cutting resistance is significantly reduced by the electrochemical reaction. However, under the conditions of a previous machining experiment, the amount of removal was low, and the machining test was conducted within a range that did
