Popis: To improve the carbonation performance of fly ash, waste incineration fly ash was subjected to high-temperature alkali fusion-hydrothermal and other treatments. The results showed that the material prepared with 8 g of sodium hydroxide, 10 h of maturation, 100 °C and 10 h of hydrothermal temperature had the best ability to isolate carbon dioxide, 521 g/kg, while the fly ash could only adsorb 160 g/kg of carbon dioxide, which improved the isolation ability by 212.5%.
