electrolysis cell for industrial production of fluorine

Toward electrochemical synthesis of cement—An

Cement production is currently the largest single industrial emitter of CO2, accounting for ∼8% (2.8 Gtons/y) of global CO2 emissions. Deep decarbonization of cement manufacturing will require remediation of both the CO2 emissions due to the decomposition of CaCO3 to CaO and that due to combustion of fossil fuels (primarily coal) in calcining (∼900 C) and sintering (∼1,450 C). Here

an electrolysis process due to the dominating losses. In an ideal cell, voltage defines the efficiency over the range of current densities. Figure 1: Schematic representation of a U/I characteristic and its indirectly proportional effect on efficiency. The so-called U/I

Electrolysis

One important use of electrolysis of water is to produce hydrogen. 2H 2 O (l) → 2H 2(g) + O 2(g) This has been suggested as a way of shifting society toward using hydrogen as an energy carrier for powering electric motors and internal combustion engines. (See hydrogen economy.

Thyssenkrupp develops new industrial

THYSSENKRUPP has launched industrial-scale water electrolysis technology to make hydrogen production economically feasible for large projects using renewable energy. Hydrogen has a lot of potential in a low-carbon future, such as energy storage in the gas grid, clean fuels, and the production of sustainable chemicals such as ammonia and methanol when renewable energy sources are used.

A Novel Fluorine Production Process in a Proton Exchange

separator could be used in a commercial fluorine cell and to evaluate catalytic activity for fluorine production on ELAT and MEA elec-trodes. The reactor was scaled up with 9 cm2 electrodes in this con-figuration to allow molten salt to drain freely in and out of the

Electrolysis

Electrolysis is the breaking down of a compound into its elements using an electric current For example, the electrolysis of zinc chloride (ZnCl 2) into its elements zinc and chlorine ZnCl 2 (s) → Zn(s) + Cl 2 (g) This method is often used to: Extract metals from their metal ores when the metals cannot be extracted by heating their ores with carbon

Multiphysics Modeling of a Fluorine Production Cell

The fluorine production process is based on the electrolysis of an anhydrous HF-composed molten salt which results in the production of fluorine at the anode and hydrogen at the cathode. Given the reactivity of the chemical species involved, simulation is a tool of choice to understand this process, to develop new technologies and to get access to local data.
