Abstract:
1. A process of producing single-walled carbon nanotubes comprising feeding a feedstock including a hydrocarbon source, a metallocene, and a sulfur compound in a state of mist to a feeding zone located between a nozzle end of a feeding nozzle and a reaction zone at a temperature of 200° C. or less where hydrogen gas flows at a linear velocity of 1 to 50 m/second wherein the amount of the hydrocarbon source is from 0.01 to 0.2% by mass and the amount of the metallocene is from 0.001 to 0.2% by mass based on the total amount of the hydrogen gas and the feedstock, and the amount by mass of the sulfur compound is from ⅛ to 4 times as much as that of the metallocene; and, making the hydrogen gas and the fed feedstock flow through the reaction zone at a temperature of 800 to 1000° C.
