BEHAVIOR OF PCDD F UNDER PYROLYSIS CONDITIONS

Results are reported for the behaviour of PCDD/F during the pyrolysis process. Investigations were performed at a rotary kiln operating as a disposal facility as well as in a laboratory-scale batch reactor. The amount of input PCDD concentration and the operating conditions seeme d not to have an impact on the PCDD mass balance. In both cases about half the input amount was found in the pyrolysis products. Contrary to that, formation rates and distribution of the generated furans depend ed largely on the operating conditions and the input composition. (C) 1997 Elsevier Science Ltd.
