Process for refining hydrocarbon oils

Patent ·
OSTI ID:7093101
An improved process for producing valuable refined products from unrefined petroleum fractions of the type of burning and lubricating oils is described. The process comprises partially refining the oil in absence of added, solid, carbonaceous materials by destructive hydrogenation in which the time of contact is adjusted to convert an appreciable amount but not more than 20% of the oil into hydrocarbons boiling below 400/sup 0/F, and then further refining the oil by extraction with a suitable non-reactive selective solvent capable of removing aromatic and unsaturated hydrocarbons.
