  4. 12. Energy efficiency in the sodium chlorate process: From electrocatalysis to pilot plant investigations

    Author : Kristoffer Hedenstedt; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sodium chlorate; corrosion; mild steel; goethite; lepidocrocite; green rust; hypochlorite reduction; hydrogen evolution; in situ electrochemical Raman spectroscopy;

    Abstract : Sodium chlorate is an important industrial chemical produced through an electrochemical manufacturing process. The global production rate is 3.6 million tons annually and consumes approximately 20 TWh of electrical power. The majority of the produced sodium chlorate is used as raw material to make chlorine dioxide for the bleaching of kraft pulp. READ MORE

  5. 13. Nanoscaled Structures of Chlorate Producing Electrodes

    Author : Christine Hummelgård; Håkan Olin; Joakim Bäckström; Svein Sunde; Mittuniversitetet; []
    Keywords : ;

    Abstract : Sodium chlorate is mainly used for production of chlorine dioxide (a pulp bleaching agent). Sodium chlorate is produced by an electrochemical process where chloride ions (from sodium chloride dissolved in water) are oxidized to chlorine on the anodes and hydrogen is evolved on the cathodes.

  7. 15. Electrochemical Investigations of Water and Hypochlorite Reduction on a-and y-FeOOH

    Author : Kristoffer Hedenstedt; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sodium chlorate; corrosion; electrodeposition; goethite; lepidocrocite; hypochlorite reduction; hydrogen evolution;

    Abstract : The cathodes in the electrochemical cells used for production of sodium chlorate process are made from mild steel. Due to the harsh environment in the chlorate cell, with oxidative species such as chlorate and hypochlorous acid, the cathodes corrodes. This corrosion might be beneficial, leading to surface enlargement and lower potential. READ MORE
