The invention relates to the field of catalysis, and discloses a reactor provided with a helical tube and an application thereof. The reactor includes a reaction cavity, a catalyst section filled in the reaction cavity, and a surrounding arranged along the outer wall of the reaction cavity. a spiral tube, the air outlet of the spiral tube is located below the catalyst section, and the distance between the air outlet of the spiral tube and the cross section of the downstream end of the catalyst section is 0.5-0.8 times the length of the catalyst section; the catalyst The catalyst in the section includes a carrier and an active component supported on the carrier, wherein the carrier is at least one of CaO, MgO and BaO; the active component is an oxide of an alkali metal. Using the purge gas as a heat carrier to remove the heat of reaction, effectively control the hot spot temperature of the catalyst bed, reduce the fly-over phenomenon, thereby inhibiting the deep oxidation of methane to a certain extent, and improving the conversion rate of methane and the selectivity and yield of carbon 2 hydrocarbons , has a good prospect of industrial application. |
