Abstract

A process is disclosed for the recovery of very viscous lubricating oils from brown-coal tar and shale tar, consisting in driving off from the crude tar or the tar freed from volatile constituents after removal of paraffin by precipitation with a volatile solvent such as acetone or one of its homologs, the light oils more or less completely with superheated steam from about 200 to 250/sup 0/C without any outside heating over a free flame.
