Patent ID: 8821692

Claim:
A method for fast pyrolysis of lignocellulose, comprising; a) mechanically comminuting the lignocellulose to lignocellulose particles while preheating the lignocellulose particles to a range of 170 to 200° C. under a low oxygen environment; b) mixing the lignocellulose particles with heat transfer particles after the mechanical comminuting and preheating so as to provide a mixture, the heat transfer particles including grains of at least one of metal, ceramic and hard material, the grains having a diameter greater than 3 mm; c) introducing the heat transfer particles, at a temperature in a range of 400° C. to 500° C. to a heat exchanger and heating the heat transfer particles, prior to the mixing, to a temperature between 500° C. and 650° C.; and d) 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.
