| 摘要 |
The invention relates to a method of carrying out pyrolysis process in a pyrolysis reactor (4) for solid fuel to produce pyrolysis oil. The method comprises supplying solid fuel into a drying zone in the pyrolysis reactor (4) for removing moisture containing gases, drying the solid fuel in the drying zone and extracting the moisture containing gases re-moved from the solid fuel out of the pyrolysis reactor (4), passing the dried solid fuel from the drying zone to the pyrolysis zone of the pyrolysis reactor (4), pyrolyzing the dried solid fuel for separating pyrolysis gases from the dried solid fuel and conducting the pyrolysis gases from the pyrolysis reactor (4) to a condenser (8) for producing pyrolysis oil.
