CO2 mineralization and sequestration provides an effective way to reduce greenhouse gas emissions,which is suitable for the lack of geological conditions of reservoir area. According to the problems of traditional mineralization technology,such as complicated processes,extreme reaction conditions and the raw materials with high prices in China,this paper proposed the CO2mineralization and sequestration technology,which used cheap fly ash as raw materials and recyclable ammonium salts NH4HSO4 as dissolution ...
