Removal of organic sulphur from coal by using peroxyacetic acid with an ultrasonic-assisted extraction system / Nurfatin Athirah Abdul Harith
Coal desulfurization is important for producing clean coal and minimising hazardous pollutants during combustion. However, organic sulfur in coal is more difficult to remove than inorganic sulfur. Therefore, in this study, a method of Jambi coal sample desulfurization using peroxyacetic acid (PAA) w...
