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 gas delivery system, comprising:
- a first conduit having a first end and a second end, wherein the first end of the first conduit is attached to a first gas source;
- a second conduit having a first end and a second end, wherein:
- the first end of the second conduit is attached to a second gas source;
- the second conduit has a length;
- the second conduit is positioned entirely within an interior of the first conduit over at least a portion of the length;
- and
- the second conduit is free from physical contact with the first conduit over the portion of the length of the second conduit;
- and
- a gas delivery port, comprising:
- the second end of the first conduit;
- and
- the second end of the second conduit, wherein the gas delivery port is configured to deliver a first gas within the first gas source through the first conduit into a reactor chamber and a second gas within the second gas source through the second conduit to the reactor chamber.
A gas delivery system, comprising:
- a reactor chamber;
- a first conduit defining a first gas delivery port into the reactor chamber;
- and
- a second conduit defining a second gas delivery port into the reactor chamber;
- wherein, in a cross section at the first gas delivery port through the first conduit:
- the second conduit is positioned entirely within the first gas delivery port defined by the first conduit;
- and
- the second conduit is free from physical contact with the first conduit.
A gas delivery system, comprising:
- a reactor chamber;
- a first conduit defining a first gas delivery port into the reactor chamber;
- a plurality of second conduits comprising a plurality of second gas delivery ports into the reactor chamber, wherein each second conduit of the plurality of second conduits defines one second gas delivery port of the plurality of second gas delivery ports;
- a first gas source comprising a first gas in fluid communication with the first conduit, wherein the first gas comprises carbon monoxide;
- and
- a second gas source comprising a second gas in fluid communication with the second conduit, wherein the second gas comprises carbon monoxide gas and a catalyst;
- wherein, in a cross section at the first gas delivery port through the first conduit:
- the plurality of second conduits are positioned entirely within the first gas delivery port defined by the first conduit;
- each second conduit of the plurality of second conduits is free from physical contact with the first conduit;
- and
- each second conduit of the plurality of second conduits is free from physical contact with any other second conduit.
