发明名称 Deodorant comprising metal oxide-carrying activated carbon.
摘要 A metal oxide-carrying activated carbon having an oxidation catalytic activity comprises a treated activated carbon obtained by carbonizing a carbon material, activating the obtained carbon with an activating gas comprising carbon dioxide and water vapor, said activating gas containing not more than 15% by volume of water vapor, and then cooling the activated carbon down to a temperature of not more than 300 DEG C under the same atmosphere; and, carried thereon, 0.1 to 20% by weight as converted into metal of an oxide of at least one metal selected from the group consisting of iron, chrome, nickel, cobalt, manganese, zinc, copper, magnesium and calcium. A deodorant is obtained by adding 1 to 50 parts by weight of a plastic powder having an average particle diameter of 1 to 50 mu m to 100 parts by weight of the above metal oxide-carrying activated carbon. The above activated carbon and deodorant exhibiting high decomposing functions for foul-odor gases such as methylmercaptan and trimethylamine and are hence usable as deodorants; they are also suitable as deodorants for refrigerators, since they have particularly high decomposing activities for these gases in low concentrations and at low temperatures.
