Method for producing nanocarbon and catalytic reaction device for producing nanocarbon

摘要

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.

主权项

1. A nanocarbon producing reactor comprising:
a cylindrical screw feeder main body as a pressure reaction vessel; a catalyst feeding portion for introducing a catalyst into the screw feeder main body; low hydrocarbon feeding means for introducing a low hydrocarbon into the screw feeder main body as a raw material gas in a space velocity value of 1,000 to 500,000 ml/g-catal./h; at least one screw rotatably provided in the screw feeder main body for conveying the catalyst and nanocarbon produced by pyrolysis of the low hydrocarbon in the feeder main body; a solid matter discharging portion provided in the screw feeder main body for discharging the catalyst and the nanocarbon conveyed by the at least one screw out of the screw feeder main body; a pressure adjusting unit for adjusting the pressure in the screw feeder main body to 10 atm or less; a gas discharging portion provided in the screw feeder main body for discharging an unreacted low hydrocarbon and hydrogen produced by the pyrolysis of the low hydrocarbon out of the screw feeder main body; and at least one external motor being connected to the at least one screw, wherein the at least one external motor is configured to operate the at least one screw back and forth, wherein the at least one screw rotatably provided in the screw feeder main body comprises a shaft to which screw blades are attached, and wherein the at least one screw is configured to rotate so as to simultaneously convey the catalyst and substantially all of the nanocarbon produced.
