<p>A method for fast pyrolysis of lignocellulose, the object being to propose an improved method for fast pyrolysis of lignocellulose that, in particular, considerably reduces the risk of undesired contamination of the pyrolysis condensate and pyrolysis coke with abraded material. The object is achieved by a method comprising mechanical comminution (2) of the lignocellulose (1) to lignocellulose particles (3); complete drying and/or preheating of the lignocellulose particles (3); mixing (5) the lignocellulose particles with heat transfer particles (6) to yield a mixture, the heat transfer particles (6) being heated, prior to mixing, to a temperature between 500°C and 650°C; and heating the lignocellulose particles by means of the heat transfer particles in a pyrolysis reactor with oxygen excluded, a temperature between 400 and 600°C being established for one to 50 seconds, and the lignocellulose particles reacting yield to pyrolysis coke (8), pyrolysis condensate (9), and pyrolysis gas (11).</p> |
