Abstract
A method and apparatus for thermolysing organic material. The method comprises steps of: A) feeding the material in a single-screw extruder (100), the extruder comprising -- a cylindrical rotor member (1) having diameter (D) and length (L) and comprising a feeding zone (14), -- the rotor member (1) arranged in a barrel (2), -- the cylindrical surface of the rotor member (1) carrying cavity/cavities and/or projection(s) (5) arranged in helically extending rows, -- the helically extending row(s) of the rotor member (1) having a pitch (P) and depth (d) in the feeding zone (14) of the rotor member, wherein -- the relation of the depth (d) to the diameter (D) of the rotor member, i.e. d:D, is not more than 1:20, and -- the relation of the pitch (P) of the rotor member to the diameter (D) of the rotor member, i.e. P:D, is not more than 1:4, B) heating the material in the single-screw extruder (100) to a flowable state, and C) thermolysing the material.
