Show full item recordAbstract
Trichloroethylene (TCE) adsorbed on different
types of active carbons was exposed to a dry and
moist air stream in the presence of 2.45 GHz microwave
radiation. Active carbon beds were used
becauae they absorb microwave energy and heatup.
The bed temperature was estimated to be from 350 to
4000°C. The extent of TCE degradation was determined
from analysis of the exit gas as well as the starting
and final bed material. The highest TCE degradation
(~80%) was observed for a carbon bed impregnated
with CuO and Cr2O3 and exposed to moist air.
Experimental results indicated that free chlorine
produced from TCE degradation is very strongly held
by active carbon. In addition, hydrogen chloride
was found in large concentration in the exit gas.
Generation of free chlorine may be avoided by using
a chlorohydrocarbon and hydrocarbon mixture on such
composition that the stoichiometry favors the production
of hydrogen chloride. The experimental
results show promise in developing new technology
for microwave-enhanced detoxification of chlorohydrocarbons.
