A method of pyrolysis (thermal decomposition) of a solid bulk organic waste and a reactor for performing the method

The invention relates to a method of pyrolysis of solid bulk organic waste, especially sewage sludge and sludge from a biogas station in a reactor (1), in which solid bulk organic waste is fed to the reaction space (320) of the reactor (1), around which a heated hollow casing (32) of the reaction space (320) is arranged, which forms a duct (3) of the heat transfer medium separated from the inner space of the reactor (1), and during the passage of the solid bulk organic waste through this reaction space (320) its pyrolysis takes place, whereby the movement of the subsequently delivered solid bulk organic waste in this reaction space (320) is decelerated by counter flow of steam and gas products formed by the pyrolysis of the preceding solid bulk organic waste. The invention also relates to a reactor (1) for pyrolysis of solid bulk organic waste, especially sewage sludge and sludge from a biogas station, in whose inner space a reaction space (320) is created, around which is arranged a heated hollow casing (32) of the reaction space (320), which is connected to the inlet (30) of the heat transfer medium to the reactor (1) and the outlet (34) of the heat transfer medium from the reactor (1), and which is separated from the inner space of the reactor (1).
