Ash Carbonation Using Carbon Dioxide Captured By Carbonates

Rise of environmental pollutants such as carbon dioxide (CO2) and oil palm waste have been a grave concern in Malaysia. In an effort to reduce the pollutants, carbonation of palm oil fuel ash (POFA) using CO2 locked in potassium hydrogen carbonates (KHCO3) was investigated at different operating con...

The best conditions obtained using complexometric titration of Ca2+ were at 800 °C (180 min) calcination, 75 °C (20 min) reaction as well as 250 rpm which have resulted in 0.0023, 0.0079 and 0.0043 g CO2 captured/g POFA used respectively.
