Abstract：Based on different raw materials and minerals of different formulation,the paper provided reference for selection of demineralization method and formulation for demineralization process.The acid-alkali demineralization method selection,main factors affecting the demineralization effect and activated carbon performance were principally introduced.In addition,the process and mechanism of acid-alkali demineralization were briefly concerned.Finally,the future research direction of the acid-alkali demineralization with activated carbon was prospected.It is mainly pointed out that the mechanism of de-ashing of the acid-alkali chemical ash removal agent should be studied deeply to realize the accurate removal of inorganic minerals in the activated carbon.The research of deep ash-removal process on coalbased activated carbon is the development trend of alkali-acid washing.
