The present disclosure provides a method for converting the target gas contained in the exhaust gas in plasma phase and an apparatus for implementing the method, the method comprising the steps of: generating a plasma in a conversion region in which the conversion of the target gas occurs; supplying, to the conversion region, a conversion promoting agent containing a conversion promoting element of which the first ionization energy is not greater than 10eV for promoting the conversion of the target gas; supplying, to the conversion region, a conversion agent that produces conversion products by combining with the dissociation products of the target gas and prevents the dissociation products from recombining into the target gas; and supplying the exhaust gas containing the target gas to the conversion region.According to the present disclosure, it is possible to increase the conversion of the target gas and reduce the energy required for the conversion process. Furthermore, this contributes to reducing the maintenance cost of the conversion apparatus, extending its service life, and making it easier to implement large-capacity conversion apparatus. The present disclosure can be applied not only to the process of removing harmful substances, but also to the process of synthesizing useful substances, such as reforming, gasification, gas to liquid, polymerization, etc. |
