Description:
Calcined coke may be treated with different types of oil in order to limit the formation of a dust cloud during loading and transportation. The method specified in this International Standard permits the determination of the loss of mass in calcined coke after elimination of oil adhering to the particles, by extraction with dichloromethane (methylene chloride) in an extraction apparatus.
