Definitions

  • zeolite crystals both natural and synthetic have a porous structure with connected channels extending through them, they have been employed as molecular sieves for selectively absorbing molecules on the basis of size, shape, and polarity.
  • this activated dry composition is a mixture of a "dry inert diluent," a metal chlorite, and a dry agent capable of reacting with the metal chlorite in a dry state to produce chlorine dioxide.
  • a dry inert diluent a metal chlorite
  • a dry agent capable of reacting with the metal chlorite in a dry state to produce chlorine dioxide.
  • such is subject to undesirable storage and shipping losses, due to outgassing of chlorine dioxide before the time of intended use of the composition.
  • the dehydrated zeolite crystals are then immersed in (or sprayed with) an aqueous solution of sodium chlorite and calcium chloride at high temperature, e.g., in the range from about 120°F to about 190°F (about 50 to about 90°C), and the resulting slurry is thoroughly mixed. Then, the mixed slurry is air dried (or allowed to equilibrate) to the desired moisture level (typically about 0-20% by weight) to produce impregnated zeolite crystals. Alternatively, the air drying step can be avoided by calculating the amount of aqueous impregnating material needed to achieve the desired final moisture level (e.g. about 15% by weight) and adding this amount to the dehydrated zeolite at the time of impregnation.
  • a single bed containing a mixture of crystals can be used as long as the mixed bed contains both impregnated zeolite crystals from the first bed described above and zeoiite crystals from the second bed described above.
  • a mixed bed of zeolite crystals zeolite crystals impregnated with sodium chlorite and calcium chloride mixed with zeolite crystals impregnated with phosphoric acid
  • chlorine dioxide e.g., by flowing a fluid through the mixed bed.
  • the impregnated zeolite crystals preferably comprise from about 1 to about 10 % by weight, most preferably from about 2 to about 10 % by weight of metal chlorite, preferably from about 2 to about 15 % by weight of at least one proton generating agent, and preferably from about 0.5 to about 2 % by weight of a water retaining substance.
  • chlorine dioxide is produced by activating (with excess protons) a zeolite crystal mixture comprising zeolite crystals impregnated with sodium chlorate, zeolite crystals impregnated with at least one reducing agent (e.g., hydrogen peroxide, ferric chloride, or peracetic acid), and optionally also zeolite crystals impregnated with calcium chloride.
  • a zeolite crystal mixture comprising zeolite crystals impregnated with sodium chlorate, zeolite crystals impregnated with at least one reducing agent (e.g., hydrogen peroxide, ferric chloride, or peracetic acid), and optionally also zeolite crystals impregnated with calcium chloride.
  • the mixture comprises equal (or substantially equal) amounts of crystals impregnated with each of the four agent.
  • the regeneration operation assumes that the zeoiite crystal mixture was initially produced with the crystals impregnated with each chemical having a distinctive size or range of sizes.
  • the mixture may comprises zeolite crystals having size in a first range impregnated with e.g. suifuric acid, zeolite crystals having size in a second range impregnated e.g. with sodium chlorate, each crystal in the second range being larger than the largest crystal in the first range, zeoiite crystals having size in a third range, each crystal in the second range being larger than the largest crystal in the second range impregnated with e.g.

Abstract

L'invention concerne la génération de dioxyde de chlore par activation d'un support solide imprégné de sels de chlore ou de chlorate et/ou d'une substance qui réagit directement ou indirectement avec ce chlore ou chlorate pour former du dioxyde de chlore, et/ou d'un agent générant un proton.
