Abstract
The heavy oil fraction of pyrolysis oil vapors containing concentrated contaminants is coked on hot heat transfer material. The coke-containing heat transfer material is then mixed with raw feed in a retorting vessel provided with an inert stripping gas of a velocity sufficient to lower the dew point of the pyrolysis oil.
