Abstract: A method for producing chlorine dioxide by moving fluid (such as air) relative to (e.g. flowing the fluid through) a first bed of zeolite crystals impregnated with at least one of the following: phosphoric acid, acetic acid and citric acid, and then moving the fluid relative to a second bed of zeolite crystals impregnated with sodium chlorite and/or zeolite crystals impregnated with chlorine. Optionally, at least some of the produced chlorine dioxide is absorbed by moving the fluid relative to (e.g., flowing the fluid through) a third bed of chemically impregnated zeolite crystals.

Abstract: A method for producing chlorine dioxide by moving fluid (such as air) relative to a first bed of zeolite crystals impregnated with sodium chlorine and/or zeolite crystals impregnated with chlorine, and by moving the fluid relative to a second bed of zeolite crystals impregnated with one of the following: phosphoric acid, acetic acid and citric acid. The first and second beds may be physically mixed together. A further aspect of the present invention relates to removing chlorine dioxide from a fluid by moving the fluid relative to a bed of zeolite crystals impregnated with one of the following: potassium hydroxide, sodium sulfite, sodium bisulfate and ferrous sulfate. This method may be used to remove chlorine dioxide produced using the method for producing chlorine dioxide described above.
