    摘要: A method for the electrochemical production of ferrate salts in an aqueous electrolyte solution comprising one or more hydroxide components. Dramatically increased yields of ferrate salts are obtained from using a mixture of sodium hydroxide and potassium hydroxide. Preferably, both sodium hydroxide and potassium hydroxide are present in concentrations greater than 5 molar, most preferably at least 10 molar, i.e., 10 M NaOH and 10 M KOH. The anode is preferably a sacrificial anode made out of an iron-containing material to supply the iron necessary for the ferrate production reaction. The aqueous hydroxide solution, even a mixed potassium hydroxide (KOH) and sodium hydroxide (NaOH) solution, may be recycled and reused in the electrochemical cell, preferably after the extraction of the ferrate salt

    摘要: Hydrogen gas production includes supplying a hydrocarbon fluid to a gap between a pair of electrodes, applying a voltage across the electrodes to induce an electrical arc, wherein the electrical arc contacts the hydrocarbon to form a plasma and produces a gaseous product comprising hydrogen gas and a solid product comprising carbon, and dynamically adjusting the gap length to control at least one parameter of the plasma. Preferably, the gap length is decreased during plasma initiation or reformation and increased to increase the hydrogen gas production rate. The method preferably includes dynamically adjusting the spatial separation of the electrodes and rotating at least one electrode while generating hydrogen gas to reduce adherence of solids to the electrodes. Furthermore, the polarity of the electrodes may be periodically reversed, primarily to reduce adherence of solids. If the hydrocarbon fluid is a liquid, the method may include controlling the level of the hydrocarbon liquid relative to the pair of electrodes.
