ABSTRACT:
A chlorine gas filtering material suitable for use in a high temperature oxygen environment, and a method of making the filtering material. The filtering material is prepared by impregnating a porous manganese dioxide and copper oxide hopcalite catalyst prepared by the carbonate method with sodium hydroxide. The process of making includes the steps of mixing the catalyst into a sodium hydroxide solution and then vacuum baking the impregnated catalyst for at least 8 hours, and preferably for 16 hours at a temperature of 240.degree. F.-260.degree. F.
