METHOD AND DEVICE FOR PYROLYSIS AND GASIFICATION OF SUBSTANCE MIXTURES CONTAINING ORGANIC CONSTITUENTS

摘要

The invention relates to a method for pyrolysis and gasification of substanc e mixtures containing organic constituents. The organic substances (4) or substance mixture containing organic constituents are brought into contact with a heat transfer medium, preferably ash (5) from a combustion reactor (2 ) and pyrolysed in a pyrolysis reactor (1), preferably a tower reactor. The pyrolysis coke (10) arising as a result of pyrolysis is combusted in a combustion reactor (2), preferably a fluidized bed reactor, with the additio n of air (11). In order to improve the above-mentioned method, the crude gas ( 6) produced by pyrolysis is purified in a crack reactor (3), preferably by a catalyst.
