Desulfurization of jambi province coal using hydrogen peroxide (H2O2) – hydrochloric acid (HCl)) pre-treatment by ultrasonic-assisted system / Nur Farah Eizlin Suhaimi

The digestion of ultrasonic assisted system and the acid leaching process are the two combining method that used to remove the total sulfur in coal sample. During this desulfurization process, the coal samples had been treated with a different ratio concentration of acidic solution. The Hydrogen Per...
