Abstract
Disposal of polychlorobiphenyls (PCBs) is a current problem still far from a really satisfactory solution.
Because of the wide use and the chemical inactivity, the PCB amount to be treated is considerably large.
In this paper, the setting-up of a methodical catalytic pyrolysis of polychlorinated compounds is
proposed. The monitoring of the final decomposition products by analytical techniques, such as GC and
coupled TG-FTIR, allowed to optimize the reaction temperature: the encouraging results, the lower
operative temperatures with respect to previous systems and the favourable prospects regarding the
environmental impact make this methodology open to practical applications at a relative low cost.
Key words: Thermocatalyzed breakdown -- polychlorinated compounds -- radical oxidation.
