Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.ABSTRACT Biomass energy plays a critical role in alleviating environmental pressures. However, its relatively high content of alkali metals (especially for potassium) would cause ash‐related issues during combustion. To mitigate these issues, the potassium migration behaviors during chestnut shell (CS) conversion and the modification mechanisms of ...

Conversion of Waste Incineration Fly Ash into Calcium Phosphates
Journal of the Society of Powder Technology, Japan, 2005 In order to convert waste incineration fly ash (Fa) into calcium phosphates, Fa was treated with Na3PO4 solutions at 85°C for 24h and the resulting materials were characterized by various means. Powder X-ray diffraction, X-ray fluorescence and thermal analysis indicated that the Fa contains large amounts of CaCO3 and Ca(OH)2.
