摘要： This invention provides improved methods for combustion synthesis of carbon nanomaterials, including fullerenes, employing multiple-ring aromatic hydrocarbon fuels selected for high carbon conversion to extractable fullerenes. The multiple-ring aromatic hydrocarbon fuels include those that contain polynuclear aromatic hydrocarbons. More specifically, multiple-ring aromatic hydrocarbon fuels contain a substantial amount of indene, methylnapthalenes or mixtures thereof. Coal tar and petroleum distillate fractions provide low cost hydrocarbon fuels containing polynuclear aromatic hydrocarbons, including without limitation, indene, methylnapthalenes or mixtures thereof.

摘要： The invention generally relates to purification of carbon nanomaterials, particularly fullerenes, by removal of PAHs and other hydrocarbon impurities. The inventive process involves extracting a sample containing carbon nanomaterials with a solvent in which the PAHs are substantially soluble but in which the carbon nanomaterials are not substantially soluble. The sample can be repeatedly or continuously extracted with one or more solvents to remove a greater amount of impurities. Preferred solvents include ethanol, diethyl ether, and acetone. The invention also provides a process for efficiently separating solvent extractable fullerenes from samples containing fullerenes and PAHs wherein the sample is extracted with a solvent in which both fullerenes and PAHs are substantially soluble and the sample extract then undergoes selective extraction to remove PAHs. Suitable solvents in which both fullerenes and PAHs are soluble include o-xylene, toluene, and o-dichlorobenzene. The purification process is capable of treating quantities of combustion soot in excess of one kilogram and can produce fullerenes or fullerenic soot of suitable purity for many applications.

摘要： Filter devices and methods for collection of carbon nanomaterials, including fullerenes, produced in gas phase reactors are provided. The filter devices provide for in situ cleaning of filters to release captured product for collection. Product can be released and removed from the reactor without disrupting continuous synthesis of carbon nanomaterials. The filter devices facilitate increased reactor operation and larger scale production of carbon nanomaterials. The filters are cleaned by application of a motive force and/or a gas flow to the filter. In a specific embodiment filters are cleaned by a reverse flow of gas pulses to the filter provided. The invention also provides reactor systems for gas phase synthesis of carbon nanomaterials that can be operated continuously employing the filter device of this invention. Preferred reactor systems are those which synthesize carbon nanomaterials by combustion. Methods for continuous production of carbon nanomaterials using the filtering devices and methods of this invention are also provided.
