Abstract:
1. A process for producing single walled carbon nanotubes, comprising: providing a fluidized bed reactor; disposing catalytic particles into the fluidized bed reactor wherein the catalytic particles comprise a support material and a catalyst, the catalyst effective in catalyzing the conversion of a carbon-containing gas into carbon nanotubes; heating the catalytic particles in the fluidized bed reactor to a reaction temperature; and exposing the catalytic particles to a carbon-containing gas at a flow rate sufficient to maintain the catalytic particles as a fluidized bed and maintaining the catalytic particles at a temperature sufficient to cause catalytic production of single walled carbon nanotubes on the catalytic particles thereby forming reacted catalytic particles bearing the single walled carbon nanotubes.
