Abstract:
The conversion of trichloroethylene (TCE) vapor (1000 cm3/m3) in humid and dry conditions has been comparatively tested over several
acidic catalists: HY zeolite, silica–alumina, tungsta–alumina, and pure -alumina. Among them, alumina shows the higher activity in TCE decomposition
to COx and HCl at lower temperature (total conversion around 820 K) and no deactivation phenomena occur at the laboratory scale
time. AddingWO3 could even enhance catalytic activity. The use of alumina catalysts, although much less active than noble-metal containing
catalysts, allows, in principle, the destruction of different chlorided organics and the recovery of HCl in a versatile authotermic process.
