| Outline of Final Research Achievements |
A highly efficient plasma catalytic system was developed for selective adsorption and subsequent decomposition of low-concentrated ethylene in air that degrades freshness of fruits and vegetables. Inserting the silica-coated and silver-loaded membrane-like catalyst tube in the tubular plasma reactor resulted in an about 4-fold increase in a rate of ethylene decomposition by periodic short-term plasma irradiation.
In addition, a flat-plate-stacked plasma catalytic reactor was designed for increasing the system size. Silica coating on the flat electrodes increased in the surface area and homogeneity of plasma discharge between the electrodes. A flat membrane-like catalyst was also prepared for adsorptive condensation of ethylene in air. The system is now built by combining the electrodes and catalysts.
