%X The paper presents
comparative kinetic characteristics of the decomposition of 2,4-dichlorophenol
in a dielectric barrier discharge and a combined plasma-catalytic process. Vermiculite
containing 5% zirconium was used as a catalyst. The destruction processes of
2,4-DCP proceed efficiently, the degree of decomposition increases in the
combined plasma-catalytic process by a factor of 1.33 and reaches 80%. The
experimental results were processed according to the first-order kinetic law (R2 > 0.97), according to which the effective constants (0.36 ¡À 0.04) and (0.51 ¡À 0.03) s-1 and the decomposition rates of 2,4-DCP (106 and 123 ¦Ìmol/l¡¤s) when treating model
solutions without a catalyst and with vermiculite + Zr 5%, respectively, and
the energy costs are 0.012 and 0.017 molecules/100eV. The main decomposition
products present in the solution have been determined to be carboxylic acids,
aldehydes, the contribution of which does
not exceed 2%, as well as chloride ions, and in the gas phase they are
carbon dioxide and molecular chlorine (the share of which does not exceed 1.5%
of total chlorine content in the system).
