Definitions

  • Plasma jet devices are widely used industrial devices. For instance, typical uses include the coating of a substrate with a metal layer produced through the melting and transporting of melted particles in a plasma jet emanating from a torch ⁇ like mechanism. Torches of similar design are also used in cutting metals.
  • Figure 2 shows a cutaway drawing of a plasma jet reactor having a plasma chamber insert especially suitable for use with the inventive process.
  • Figure 3 shows an NMR spectrograph of the product.produced in the Example.
  • This invention is a process for the production of fullerene-containing products.
  • the process generally involves the introduction of particulate carbon-containing feedstock into a plasma jet reactor having an insert which contacts the plasma and maintains the reaction volume at a high temperature level and which uses a plasma gas which preferably is one or more of the noble gases.
  • the temperature of the interior of the insert should be ot least 500° C, preferably at least 1000° C, and most preferably 1500° C.
  • the inside diameter of the insert is less than about twice the size of the diameter of the plasma gun nozzle.
  • the insert need not adhere to the listed desired physical dimensions if it is heated by soe other means, e.g., by direct resistive heating or by R.F. induction heating of the insert.
  • the plasma generator is made up of a cathode (202) and an anode (204) which also serves as a nozzle to accelerate the plasma gas supplied to the plenum (206) between the cathode (202) and anode (204) through gas supply line (208) .
  • Cooling water may be introduced through supply line (210) and withdrawn through line (212) .
  • Carbon powder may be supplied into the plasma flame found in plenum (206) through line (214) .
  • the plasma gases leave the plenum (206) and proceed down the open pathway (216) downstream of the plenum
  • Argon flow was initiated to the arc and the arc ignited. Operating arc voltage was 30-35 volts and arc current was adjusted to 700-950 amperes. The carbon powder flow was started, with 21.6 SCFH of helium, and the voltage and current were monitored for the .length of the run.

Abstract

Procédé de production de fullerènes utilisant du plasma. On achemine de la poudre de carbone par un conduit (214) jusqu'à une flamme de plasma située dans une chambre (206) se trouvant entre une cathode (202) et une anode (204). Les gaz de plasma quittent la chambre (206) et se dirigent dans un passage (216). Le passage (216) est revêtu d'un insert réfractaire (217) maintenant la température suffisamment élevée pour permettre le recuit de précurseurs de fullerènes en mollecules de fullerènes.
