PURPOSE: To offer an air-purifying agent with mechanical strength to be wrapped on the base of light weight by wrapping the soluble oxidizer on the mineral fiber paper. n CONSTITUTION: after the mineral fiber paper made from mineral short fiber and made into desirable shape and size, for instance, such carriers as ceramic paper honeycomb of alumina silica family, is dipped in such soluble oxidizer as KMnO 4 water solution and the like, the same is dried up to produce an air-purifying agent. The air-purifying agent thus produced is charged into the column and the like, and a wide scope of air pollutants or smelly substances such as H 2 S, SO 2 , NO x methyl mercaptan and the like are removed by passing the air containing pollutants or smelly substances through the said air-purifying agent charged in the column. n COPYRIGHT: (C)1987,JPO&Japio |
