Abstract

See full text

Disclosed is a method for reducing the tar content in pyrolysis gas generated in a pyrolysis reactor (1). The method comprises the steps of: guiding the pyrolysis gas through a filter (2) to remove at least 90% of all the particles in the pyrolysis gas having a particle size down to 7 μ and preferably down to 4 μ from the pyrolysis gas, partially oxidizing the pyrolysis gas in a partial oxidation reactor (3) to remove tar from the pyrolysis gas, and guiding the pyrolysis gas through a coke bed (4) to further remove tar from the pyrolysis gas. Furthermore, a two-stage gasifier (6) is disclosed.
