METHOD, SYSTEM AND INJECTION SUBSYSTEM FOR PRODUCING NANOTUBES
A floating catalyst chemical vapor deposition system produces nanotubes. The system includes a reaction chamber, a heater for heating a nanotube-material precursor and a catalyst precursor, and an injector for injecting the precursors into the chamber. In the chamber, the catalyst precursor is pyrol...

| description | A floating catalyst chemical vapor deposition system produces nanotubes. The system includes a reaction chamber, a heater for heating a nanotube-material precursor and a catalyst precursor, and an injector for injecting the precursors into the chamber. In the chamber, the catalyst precursor is pyrolysed to produce catalyst particles, and the nanotube-material precursor is pyrolysed in the presence of the catalyst particles in order to produce nanotubes. A controller controls at least one operational parameter, e.g., injection temperatures of the precursors, flow rates of carrier gases of the precursors, and a reaction temperature of the chamber and of the precursors. An injection pipe extends into the chamber to an adjustable extent in order to control the injection temperature of the catalyst precursor and/or the nanotube-material precursor. |
