Preferred Label : residual fuel/oil;
IUPAC definition : The liquid or semi-liquid, high-boiling fraction of residue from the distillation
of petroleum which is used as a fuel. After removal of the lower boiling fraction
of crude oil, sold as petroleum gas, the somewhat higher boiling fraction becomes
gasoline and diesel oil. A portion of the higher boiling fraction is 'cracked' to
yield additional gasoline. Still heavier oils become lubricants. paraffin, asphalt,
etc., are also extracted from the crude oil. It is the remaining residual oil, not
economically usable for other industrial purposes, which is then sold as a relatively
low cost fuel for burning.;
