Pyrolytic oils produced by the pyrolysis of forestry residues in a vertical bed, countercurrent flow reactor have been thoroughly characterized. The pyrolytic oils were produced in a 500-lb. per hour pilot plant and in a 50-ton per day field development facility. The overall chemical and physical properties have been determined by standard analytical techniques. The oils are dark brown to black with a burnt, pungent odor and have a boiling range of about 100C to approximately 200C at which point thermal degradation begins to occur. Pyrolytic oils contained phenolics, polyhydroxy neutral compounds and volatile acidic compounds.
