Zusammenfassung: | The invention relates to an alkaline method for preparing nanometer white carbon black and aluminum polychlorid through ash of oil shale. The alkaline method comprises steps of firstly grinding and calcining the ash of the oil shale, then dissolving in alkali and separating, preparing white carbon black with the separated solution, and preparing the aluminum polychlorid with filter cakes. The alkaline method can be used for preparing the aluminum polychlorid solution, which has over 93% of purity, more than 94% of whiteness, over 50% of white carbon black and basicity, and 68% of turbidity removal rate, thus having obvious economic benefits, environment benefits and social benefits. |
