US_2021009415_A1

Resumen de: EP3767010A1

Disclosed is an electrochemical method for high-temperature molten salt electrolysis in humid atmosphere, which relates to the technical field of electrochemical metallurgy. The method involves preparing hydrogen gas, metals/alloys, metal oxide compounds and metal hydrides in humid high-temperature molten salt environment. Hydrogen gas is generated by electrolyzing water in a molten salt electrolyte at above 100° C, and with a working cathode being a solid-state oxide pellet and a voltage applied to the electrolyzing cell being far lower than that in a direct electro-deoxidation process, the hydrogen gas generated reduces solid-state oxide cathodes to produce metals. The hydrogen ions in the molten salt can be prepared by hydrolysis reaction of the molten salt in a water vapor containing atmosphere. Corresponding metals or alloys or metal oxide compounds can be prepared by reducing iron oxide, molybdenum oxide, tantalum oxide, nickel oxide, copper oxide, titanium oxide or corresponding compound oxides and the like. Corresponding metal hydrides can be prepared by hydrogenating solid-state metallic cathodes with the hydrogen gas generated from the molten salt electrolysis. The present method is a novel environmentally-friendly metallurgical process with short workflow and low energy consumption.
