Method for heat treating serpentine for permanent fixing carbon dioxide

2008 
A method for pre-processing serpentine for carbon dioxide permanent fixation is provided to remove adsorbed water molecules, -OH groups and other impurities remaining on non-treated serpentine through thermal treatment. A method for pre-processing serpentine for carbon dioxide permanent fixation comprises: a first step of separating pulverized serpentine into 38mum or less based on its particle size(10); a second step of thermally treating the separated serpentine(20); and a third step of cooling the thermally treated serpentine(30). The thermal treatment is performed at 600~650‹C. The thermal treatment is performed for 1 hour or more. The thermal treatment is performed under nitrogen purge condition.
