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.
