Abstract
A gas delivery system and method for delivering reactants such as a first gas through a first conduit and a second gas through at least one second conduit, for example, through a plurality of second conduits. The plurality of second conduits may each have a length, wherein at least a portion of the length is entirely disposed within the first conduit. In an implementation, the first conduit may deliver carbon monoxide and the one or more second conduits may deliver carbon monoxide doped with a catalyst such as iron pentacarbonyl. The first and second gases may be introduced into a reaction vessel such as a reactor chamber and used to form carbon nanotubes.
Claims20
A system for forming carbon nanotubes, the system comprising:
- a first conduit configured to introduce a carbon monoxide gas into a reaction vessel;
- and
- a plurality of second conduits configured to introduce catalytic particles into the reaction vessel, wherein:
- each second conduit of the plurality of second conduits comprises a length;
- at least a portion of the length of each second conduit is disposed entirely within the first conduit;
- each second conduit of the plurality of second conduits is spaced from each adjacent second conduit over the portion of the length;
- and
- each second conduit of the plurality of second conduits is free from physical contact with the first conduit over the portion of the length.
A system for forming carbon nanotubes, the system comprising:
- a first conduit configured to introduce carbon monoxide gas into a reaction vessel;
- a second conduit configured to introduce catalytic particles into the reaction vessel, wherein the second conduit comprises a length, and at least a portion of the length is disposed entirely within the first conduit;
- and
- at least one thread, channel, or rifling, or combinations thereof, in at least one of an interior of the first conduit and an interior of the second conduit, wherein the at least one thread, channel, or rifling is configured to impart a swirling motion to at least one of a carbon monoxide gas as it exits the first conduit into the reaction vessel and catalytic particles as they exit the second conduit into the reaction vessel.
A system for forming carbon nanotubes, the system comprising:
- a reaction vessel;
- a first conduit and a carbon monoxide gas within an interior of the first conduit, wherein:
- the first conduit opens into the reaction vessel at a gas delivery port and the first conduit is configured to introduce the carbon monoxide gas into the reaction vessel;
- a second conduit and a plurality of catalytic particles within an interior of the second conduit, wherein:
- the second conduit comprises a length;
- at least a portion of the length of the second conduit is disposed entirely within the first conduit;
- the second conduit opens into the reaction vessel at the gas delivery port;
- and
- the second conduit is configured to introduce the plurality of catalytic particles into the reaction vessel;
- and
- at least one thread, channel, or rifling, or combinations thereof, in at least one of the interior of the first conduit and the interior of the second conduit, wherein the at least one thread, channel, or rifling is configured to impart a swirling motion to at least one of a carbon monoxide gas as it exits the first conduit into the reaction vessel and the plurality of catalytic particles as they exit the second conduit into the reaction vessel.
