Abstract: Provided are a reactor for producing hydrogen and carbon through methane pyrolysis by a thermal storage method, and a combination reactor including the same, wherein the reactor includes a reaction unit in which pure-oxygen combustion of carbon and pyrolysis of methane are carried out, a first accommodation unit that supplies oxygen and the carbon to the reaction unit or accommodates carbon and hydrogen obtained by the pyrolysis of the methane, a flame supply unit that generates a flame within the reaction unit, a thermal storage unit that is located within the reaction unit and stores combustion heat generated during the pure-oxygen combustion of the carbon, and a second accommodation unit that accommodates carbon dioxide produced by the pure-oxygen combustion of the carbon or supplies methane to the reaction unit, wherein the pure-oxygen combustion of the carbon and the pyrolysis of the methane are alternately carried out.
