EFFECT OF MODIFIED FERROELECTRIC ON NONTHERMAL PLASMA PROCESS FOR TOLUENE DECOMPOSITION

The effect of non-thermal plasma (NTP) with different packed materials on toluene removal was studied at room temperature and atmospheric pressure. The difference among three types of NTP tests (no packed materials, with BaTiO3 rings and with Ba0.8Sr0.2Zr0.1Ti0.9O3 rings) packed into the plasma reactor, were compared in terms of energy density, toluene removal and energy efficiency. Specially, Ba0.8Sr0.2Zr0.1Ti0.9O3 as a special type of modified ferroelectric materials was manufactured by us in the laboratory. The results show that the modified ferroelectric of Ba0.8Sr0.2Zr0.1Ti0.9O3 in the plasma reactor enhances removal and energy efficiency significantly. Toluene removal efficiency of 97% can be obtained with Ba0.8Sr0.2Zr0.1Ti0.9O3 as the packed material, being 16% higher than with BaTiO3 as I lacked materials. Ba0.8Sr0.2Zr0.1Ti0.9O3 shows better ferroelectric properties than BaTiO3, as packed material of the modified ferroelectric in NTP technology.
