A cylindrical screw feeder main body, catalyst feeding portions for introducing a catalyst into the screw feeder main body, low hydrocarbon feeding portions for introducing a low hydrocarbon into the screw feeder main body as a raw material, a screw for conveying the catalyst and nanocarbon produced by pyrolysis of the low hydrocarbon in the feeder main body, a solid matter discharging portion for discharging the catalyst and the nanocarbon conveyed by the screw out of the screw feeder main body and a gas discharging portion for discharging the unreacted low hydrocarbon and hydrogen produced by the pyrolysis of the low hydrocarbon out of the screw feeder main body are provided. Nanocarbon grown with the catalyst as top with time is continuously discharged out of the screw feeder main body while unused catalyst is being fed thereto at the same amount as that of nanocarbon, allowing efficient continuous reaction.

Method for producing nanocarbon and catalytic reaction device for producing nanocarbon
