  • Patent number: 10465128
    Abstract: A thermal cracking apparatus and method includes a body having an inner volume with a longitudinal axis, where a reaction zone surrounds the longitudinal axis. A feedstock process gas is flowed into the inner volume and longitudinally through the reaction zone during thermal cracking operations. A power control system controls electrical power to an elongated heating element, which is disposed within the inner volume. During thermal cracking operations, the elongated heating element is heated to a molecular cracking temperature to generate the reaction zone, the feedstock process gas is heated from the elongated heating element, the power control system uses a feedback parameter for adjusting the electrical power to maintain the molecular cracking temperature at a substantially constant value, and the heat thermally cracks molecules of the feedstock process gas that are within the reaction zone into constituent components of the molecules.

  • Publication number: 20120325648
    Abstract: The present invention refers to a new and low cost method for producing single wall nanotubes and other allotropic forms of carbon. Said method uses a high electric current and 127 VAC or 220 VAC power supplies to sublimation of a solid precursor, which material can be made of graphite. The solid precursor is connected to metallic electrodes, so that an intense electric current cross the contacts to pulverize the graphite under high temperature. The carbon materials are deposited in the wall of the reactor as well as in the electrodes, in an atmospheric pressure. The obtained material is purified in acids and, then, the carbon nanotubes are separated. In general, this new synthesis is characterized by the absence of a metal catalyst, the employ of a short circuit current with an agent to produce carbon materials, the low pressure into reaction, and the assembly of the apparatus involving a very low cost and a low voltage of operation.

  • Patent number: 7816619
    Abstract: A process for manufacturing carbon nanotubes, including a step of creating an electric arc in an electric field between a carbonaceous anode and a carbonaceous cathode under conditions effective to produce the carbon nanotubes, wherein the carbonaceous anode and the carbonaceous cathode are immersed in dielectric liquid serving as a dielectric, coolant and for providing an oxygen-free environment. Preferably, one of the electric discharge machining dielectric oils is used as dielectric liquid. Preferably, an electric discharge machine is used to immerse the electrodes in the dielectric liquid, create an electric field, induce the arc, and adjust the gap between the electrodes thus optimizing the yield of carbon nanotubes. The process is cost-effective, easy to implement, and provides high-quality carbon nanotubes while eliminating the need for dedicated equipment and catalysts.

  • Publication number: 20100219383
    Abstract: The present invention generally relates to methods and apparatus for the synthesis or preparation of boron-doped single-walled carbon nanotubes (B-SWCNTs). The invention provides a high yield, single step method for producing large quantities of continuous macroscopic carbon fiber from single-wall carbon nanotubes using inexpensive carbon feedstocks wherein the carbon nanotubes are produced by in situ boron substitutional doping. In one embodiment, the nanotubes disclosed are used, singularly or in multiples, in power transmission cables, in solar cells, in batteries, as antennas, as molecular electronics, as probes and manipulators, and in composites. It is another object of this invention to provide macroscopic carbon fiber made by such a method.

  • Publication number: 20100176349
    Abstract: A method for separating fractions of single-walled carbon nanotubes includes exposing a solution containing fractions of single-walled carbon nanotubes to a reducing agent and separating the resulting reaction products. An alternate method for separating fractions of single-walled carbon nanotubes includes exposing a solution containing fractions of single-walled carbon nanotubes to an oxidizing agent and separating the resulting reaction products. A third method for separating fractions of single-walled carbon nanotubes includes exposing a solution containing fractions of substantially non-functionalized single-walled carbon nanotubes to a charge transfer complex agent and separating the resulting reaction products. These methods allow the production of single-walled carbon nanotubes of approximately 95 to 99% metallic and semiconducting types.
