| Abstract Scope |
In this research, the high ash and sulphur contents of Akunsa coal, Nigeria was successfully reduced. The ash and sulphur contents of the coal as received was determined to be 38 and 1.98%, respectively and were reduced by leaching the coal using sodium carbonate, nitric acid and sodium carbonate acidified in nitric acid at varying reagent concentrations, contact time and constant temperature of 90℃.
The results obtained showed that the three leachant successfully reduced the ash and sulphur contents of the coal. However, nitric acid was found to be more potent in sulphur reduction than sodium carbonate, while sodium carbonate was more effective in ash reduction than nitric acid. It was further observed that the 1.5M sodium carbonate acidified in 1M nitric acid gave the highest leaching efficiency for the same pulp density as the ash was reduced by 76.8% to 8.8% and the sulphur reduced by 82.3% to 0.35%. |
