Abstract

Some of the chlorinated organic compounds are widely used commercially, because of their advantageous chemical/physical properties or having toxicity for pestiferous living substances. However, emitted into the atmosphere they are responsible for diminishing the ozone layer in the stratosphere. Therefore, a lot of effort is devoted in finding proper solutions to decompose these chemicals in environmentally friendly ways. Platinum on different carriers play very important role in catalytic hydrodechlorination of these compounds. We have found that Pt-containing Y-FAU zeolite is an active catalyst in the hydrodechlorination of trichloroethene. IR spectroscopic experiments showed that the final products are ethane and HCl, and the hydrogen/reactant ratio exerts large influence on the rate of the hydrodechlorination reaction.
