Abstract

See full text

Method for fast pyrolysis of lignocellulose including: mechanically comminuting the lignocellulose to lignocellulose particles; at least one of completely drying and preheating the lignocellulose particles; mixing the lignocellulose particles with heat transfer particles so as to provide a mixture; heating the heat transfer particles, prior to the mixing, to a temperature between 500° C. and 650° C.; and heating, in a pyrolysis reactor with oxygen excluded, the lignocellulose particles using the heat transfer particles so as to establish a temperature between 400° C. and 600° C. for 1 to 50 seconds and so as to react the lignocellulose particles so as to provide pyrolysis coke, pyrolysis condensate, and pyrolysis gas.
