A method serves for the pyrolysis and gasification of substance mixtures containing organic constituents. The organic substances (4) or the substance mixture containing the organic constituents are brought into contact with a heat transfer medium, for preference the ash (5) from a combustion reactor (2) in a pyrolysis reactor (1), for preference a shaft reactor and pyrolysed. The pyrolysis coke (10) derived from the pyrolysis is combusted in a combustion reactor (2), for preference a fluidised bed reactor, under the admission of air (11). In order to improve such a method, the raw gas (6) generated by the pyrolysis is purified in a crack reactor (3), for preference by a catalyst
A method for the pyrolysis and gasification of substance mixtures containing organic constituents,
The method according to one of the foregoing claims, characterised in that the purification is carried out under the addition of water vapour (8).
The method according to one of the foregoing claims, characterised in that the pyrolysis coke (7) from the pyrolysis reactor (1) is used as the catalyst for the raw gas (6).
The method according to one of the foregoing claims, characterised in that a fine fraction (16) is separated (14) from the organic substances (4) prior to the pyrolysis (FIG. 2).
The method according to one of the foregoing claims, characterised in that a synthesis gas (17) is produced by the purification of the raw gas.
The method according to one of the foregoing claims, characterised in that a synthesis gas (9, 26) is produced by the purification of the raw gas (6).
The method according to one of the foregoing claims, characterised in that the combustion reactor (2) is operated as a two-stage process (FIG. 5).
The method according to one of the foregoing claims, characterised in that a zone of the pyrolysis reactor (1) is used as a crack reactor (FIG. 6;
The method according to one of the foregoing claims, characterised in that the raw gas (6) purified in the crack reactor (3) is further purified (FIG. 7) in a further reactor (32) with a catalyst deposit, or that the crack reactor is designed as a reactor with a catalyst deposit.
The method according to one of the foregoing claims, characterised in that the catalyst is added and becomes effective together with the heat transfer medium (FIG. 10).
