Outline of Final Research Achievements

Atmospheric non-equilibrium plasma induced substrate-less DeSOx filter is proposed for improvement of low temperature activation in dry desulfulization. It was clear that low temperature desulfurization performance is improved by the generation of ozone applied barrier discharge plasma. However, in detail of mechanism why SO2 absorption performance is improved by generation of ozone is not proclaimed. in our future work, clarification of this mechanism must be investigated.
Miniaturization is achieved by substrate-less MnO2 DeSOx filter in according to remove honeycomb substrate which is occupied about half volume of DeSOx filter in comparison with conventional MnO2 DeSOx filter supported on honeycomb substrate. Its volume became 5 times smaller than conventional filter. However, this result falls short of expectations because of heat degradation of MnO2. So, more small filter can be achieved by improvement of heat treatment.
