  • Publication number: 20120255866
    Abstract: This invention relates to a method for producing electrolyzed water. Firstly, HCl is injected into an area for electrolysis provided with a negative and positive electrode plate respectively on its two inner sides and several small-sized electrolysers. Then water is led into an area for water transport communicating with an electrolytic cell compartment by a retaining valve. Herein, electrolytic reaction occurs in the area for electrolysis. During such process, when the positive and negative electrode plates are electrified, HCl is decomposed to chlorine and hydrogen bubbles, which float up and store into a gas buffer area. For the pressure difference between the electrolytic cell compartment and the cell compartment for water transport, the chlorine and hydrogen in the gas buffer area enter the cell compartment for water transport through the retaining valve and form HCLO with high stable concentration, high production efficiency and environmental friendly functions of sterilization and disinfection.

  • Publication number: 20080169202
    Abstract: The present invention relates to process to prepare a chlorine-containing compound using an aqueous salt solution containing at least 100 g/l of sodium chloride and a contaminating amount of polyvalent cations comprising the steps of (i) preparing an aqueous salt solution containing at least 100 g/l of sodium chloride and at least 0.01 ppm of polyvalent cations by dissolving a sodium chloride source in water, (ii) adding an effective amount of at least one positive retention enhancing component to the aqueous solution, (iii) subsequently subjecting the solution to a nanofiltration step, thereby separating the solution into a retentate which is enriched for polyvalent cations and a permeate which is the purified aqueous salt solution, (iv) reacting the chloride anions in the permeate to a chlorine- containing compound by an electrolysis step, and (v) recycling at least part of the retentate to dissolution step (i).

  • Patent number: 7285194
    Abstract: A conductive diamond electrode including a conductive substrate comprising a carbonaceous material, a conductive diamond catalyst layer formed on a surface of the conductive substrate, and a carbon fluoride formed on an exposed portion present on the surface of the conductive substrate. The formed carbon fluoride prevents the conductive substrate from contacting with an electrolytic solution, thereby suppressing corrosion of the substrate. A long life of the electrode can be attained.

  • Publication number: 20070215484
    Abstract: A method of making hydrocarbons from polyalcohols, such as carbohydrates. The polyalcohols and carbohydrates may be provided from biomass, including paper, cardboard or urban generated paper product waste; wood and wood products, including forest slash and deadfall; agricultural waste; and the like. The polyalcohols and carbohydrates are combined with hydroiodic acid in aqueous solution to form the hydrocarbon and elemental iodine. Hydroiodic acid is then electrochemically regenerated by reducing the elemental iodine in a parallel reaction. A method of electrochemically generating hydroiodic acid from elemental iodine in aqueous solution is also described.
