Patent ID: 8043391

Claim:
A method for producing and preparing fast pyrolysis products from a biomass for entrained-flow pressure gasification, the method comprising: heating the biomass under exclusion of oxygen in a pyrolysis reactor, a temperature of between 400 to 600° C. being established for one to 50 seconds, such that the biomass reacts to form porous pyrolysis coke, pyrolysis condensate and pyrolysis gas; drawing off the pyrolysis gas; and condensing vaporous constituents of the pyrolysis condensate in a plurality of condensation stages so as to: condense, in a first condensation stage, at temperatures above the dew point of water, a low-temperature carbonization tar from the vaporous constituents; and condense and separate, in at least one subsequent condensation stage, at temperatures between 0° C. and the dew point of water, an aqueous solution of oxygen-containing organic compounds.
