  • Patent number: 7396520
    Abstract: A mod of combustion and a multi-component reactor to accomplish this mode of combustion are disclosed which produces fullerenes and fullerenic material by combustion. This mode consists of de-coupling an oxidation region of a flame from a post-flame region, thus giving greater control over operating parameters, such as equivalence ratio, temperature, and pressure; allows conditions of the operating parameters of the combustion reaction to be attained which would not be easily attained by conventional methods; and offers the ability to more easily stabilize the combustion reactions to allow for higher throughputs of fuel and oxidant. Several embodiments of a primary zone of a multicomponent reactor are also disclosed. Said primary zone serves as the oxidation region, operates on the principle of providing recycle to the reacting combustion mixture, and which may be operated as approximately a well-mixed reactor.

  • Publication number: 20040057896
    Abstract: A method of processing fullerenes includes generating a gas stream having suspended soot particles and condensable gases, wherein the condensable gases comprise fullerenes, and separating at least a portion of the condensable gases from the suspended soot particles using a gas/solid separations process. At least a portion of the fullerenes in the condensable gases can be condensed and collected after separation of the condensable gases.
