ABSTRACT:
A process is disclosed for upgrading a hydrogenated distillate oil by extracting nitrogen compounds from the oil. In the process, these compounds are selectively extracted from the oil in a liquid-liquid extraction using as the extracting medium a solution of ferric chloride in furfural. Following intimate contacting of the oil with the extracting solution, the resulting mixture is separated into an oily raffinate phase and a solvent-extract phase. The raffinate oil is especially suitable as a feedstock for a catalytic cracking or hydroprocessing stage employing an acidic catalyst. The extraction is carried out under moderate conditions of temperature and pressure.
