- IRON-ZINC COMPLEX METAL OXIDE COATED ACTIVATED CARBON ADSORBENT FOR ACIDIC GAS REMOVAL AND MANUFACTURING METHOD THE SAME

摘要

The present invention relates to an activated carbon adsorbent for removing acidic gases containing iron-zinc composite metal oxides, powdered activated carbon and silicates. A method for producing iron-zinc composite metal oxide, comprising the steps of: a) heating and mixing a solution containing an iron salt, a zinc salt, a first basic metal compound and water to prepare an iron-zinc composite metal oxide, b) preparing a powdered activated carbon mixture comprising powdered activated carbon and silicate And c) mixing the iron-zinc composite metal oxide and the powdered activated carbon mixture to produce an activated carbon adsorbent for removing an acidic gas.
