Abstract: The present invention relates to a fluidized catalyst methanation reactor. Carbon dioxide gas generated by burning organic materials to obtain power and heat, nuclear power generation, solar power generation, wind power generation, and tidal power generation due to ebb and flow are power energy that cannot be controlled according to demand. A reaction of electrolyzing water with such excess power to obtain hydrogen and making hydrogen react with carbon dioxide gas to produce methane is an exothermic reaction, and a catalyst is discharged to a catalyst elevator by placing a vibration plate in a lower part of a reactor to vibrate by absorbing the exothermic heat to maintain a constant reaction temperature and to allow the catalyst to flow inside the reactor. Also, the catalyst elevator transfers and introduces the catalyst to the upper part of the reactor, so the catalyst inside the reactor always flows to the lower part. Then, the reaction occurs by making a raw material gas flow upward, and the heat generated by the reaction is absorbed by the flowing catalyst to control the reaction temperature.
