| 摘要 |
The invention relates to a method and an apparatus for producing pyrolysis oil by generating pyrolysis steam by flash pyrolysis of raw material containing extractive compounds and condensing the pyrolysis steam into a pyrolysis liquid. According to the invention, most of the extractive based compounds are separated from the pyrolysis liquid obtained via the pyrolysis to produce a pyrolysis oil of improved quality, and at least part of the separated fraction containing extractives is recovered, processed further and/or utilized. The apparatus of the invention comprises a pyrolyzer (1), a condenser (2), at least one separating device (3) for the separation of extractive based compounds and at least one means (4, 5, 6, 7) for the recovery, further processing and/or utilization of the fraction containing extractives. |
