Abstract

A process for purifying used oil and the like comprising reacting the oil with a treating agent that will form solids from the ash-forming components of the oil, separating the solids from the oil, and subjecting at least a portion of the oil to a two stage hydrotreatment with interstage removal of hydrogen sulfide and/or ammonia.
