Abstract
The present development is a reactor system for the production of nanostructures. The reactor system comprises a conical reactor body designed to maintain an upwardly directed vertical plasma flame and hydrocarbon flame. The reactor system further includes a metal powder feed that feeds into the plasma flame, a cyclone and a dust removal unit. The system is designed to produce up to 100 grams of metal oxide nanomaterials per minute.
Claims14
In a reactor system for producing nanostructures wherein the reactor system comprises a reaction chamber having a flame source, and a powder feeder to disperse a material for producing nanostructures into the flame, and a separation means to receive and separate the produced nanostructures and unreacted dispersed material and to isolate the produced nanostructures, the improvement comprising:
- providing a reaction chamber that defines a bottom and a top and that has a flame source located at the bottom and wherein the top is adapted to allow materials from the reaction chamber to be transferred to the separation means, and wherein the reaction chamber is oriented such that a flame produced by the flame source projects upwardly into the reaction chamber, and wherein the flame is a combination of a plasma flame and a hydrocarbon flame, and wherein (a) the plasma flame is introduced at the bottom of the reactor body and the hydrocarbon flame is introduced through an inlet port positioned along the reactor body, or (b) the hydrocarbon flame is introduced at the bottom of the reactor body and the plasma flame is introduced through an inlet port positioned along the reactor body.
In a reactor system for producing nanostructures wherein the reactor system comprises a reaction chamber having a flame source, and a powder feeder to disperse a material for producing nanostructures into the flame, and a mechanical separator to receive and separate the produced nanostructures and unreacted dispersed material and to isolate unreacted dispersed material in a container that is in communication with the separator, the improvement comprising:
- providing a reaction chamber that has a cone-shaped configuration with a narrow end of the cone formed adjacent to the flame source and a wide end of the cone closed with a cap adapted to allow materials from the reaction chamber to be transferred to the separator, and wherein the reaction chamber is oriented such that a flame produced by the flame source projects upwardly into the reaction chamber, and wherein the flame is a combination of plasma flame and hydrocarbon flame, and wherein (a) the plasma flame is introduced at the bottom of the reactor body and the hydrocarbon flame is introduced through an inlet port positioned along the reactor body, or (b) the hydrocarbon flame is introduced at the bottom of the reactor body and the plasma flame is introduced through an inlet port positioned along the reactor body.
