A method for producing a pyrolysis oil is described. In said method, a feedstock to be treated is first pyrolyzed in a pyrolysis zone, in which the feedstock is heated to a temperature of 250 degrees Celsius to 700 degrees Celsius; and pyrolyzed solids and pyrolysis vapors are formed. The pyrolysis vapors are then reformed at a temperature of 450 degrees Celsius to 1,200 degrees Celsius in a post-conditioning zone, in which the pyrolysis vapors are brought into contact with a catalyst bed, wherein the pyrolysis oil is formed. In this case, the catalyst comprises a pyrolyzed solid, which can be obtained according to the pyrolysis, described above. Finally the pyrolysis oil is separated from the additional pyrolysis products, which are formed, in a separation unit.

Pyrolysis oil and method and system for the production thereof

Systems and methods for thermocatalytic treatment of material are provided. The system can have a charging region to supply starting material, a preconditioning zone in which preconditioned material is formed from the starting material, a pyrolysis zone in which pyrolyzed material is formed from the preconditioned material, and a separation unit for separation of the pyrolyzed material. In the preconditioning zone and the pyrolysis zone, a heater can be provided for heating of the material. Also provided in the pyrolysis zone are recirculation means with which a solid portion of the pyrolyzed material can be recirculated directly into the region of the pyrolysis zone facing toward the preconditioning zone.
