| titleOfInvention | Method of Asbestos Detoxification |
| abstract | The present invention relates to a method for detoxifying waste materials containing asbestos, and more particularly, to a method for more effectively detoxifying waste asbestos separated from waste materials containing asbestos through acid treatment or heat treatment followed by carbonation. The method for detoxifying waste materials containing asbestos according to the present invention comprises: a crushing step of pulverizing the waste materials containing asbestos and separating the waste asbestos; Acid treatment step of mixing the waste asbestos with acid; Heat treatment step of heating the primary carbonation treatment waste asbestos at a temperature of 350 to 500°C for 1 to 3 hours; A catalytic treatment step of cooling the heat treated waste asbestos and mixing it with a catalyst; Including a secondary carbonation step of supplying and reacting CO 2 to the catalyst-treated waste asbestos while maintaining a temperature of 100 to 150°C and a pressure of 5 to 8 bar, the catalyst treatment step is among MgO, Mg(OH)2, and NaCl. It provides, characterized in that made while using as a catalyst at least one aqueous alkali solution dissolved in water. |
