Plasma reaction, apparatus for decreasing NOx by occlusion catalyst using the same

A plasma reactor comprising:

• a furnace being hollow and having a cylindrical shape;
• a base forming a bottom of the furnace;
• a discharge opening formed at one in upper side of the furnace;
• a gas inflow opening formed on outer circumference of the furnace;
• a heat absorption path formed within a wall frame of the furnace and having a coil shape, the heat absorption path allowing a gas flowing in from the gas inflow opening to move and absorb heat;
• a mixing chamber formed inside the base and connected to the heat absorption path;
• an inflow hole formed at a lower portion of the furnace and connecting the mixing chamber and an inside of the furnace;
• an electrode having a conical shape, spaced from an inner wall of the furnace, fixed to the base and protruding from the base into an upper side of the furnace, the electrode generating a discharge voltage for a plasma reaction inside the furnace;
• a heat absorption chamber formed inside and enclosed by a conical shaped portion of the electrode and directly connected to the mixing chamber;
• and
• a liquefied fuel injection unit fixed to the base and supplying liquefied fuel to the heat absorption chamber of the electrode.
