A process is disclosed for denitrification of a hydrogenated oil, which is particularly applicable to coal-derived oils. The oil is first coked to yield a solid coke product and a coker oil having a reduced nitrogenous compound content. The coker oil nitrogen compounds are then selectively removed from the oil by liquid-liquid extraction using a solution of ferric chloride in furfural as the extracting medium. The extraction is carried out under moderate conditions of temperature and pressure.
