Method for producing fullerenes
First Claim
Patent Images
1. A method for producing fullerenes, comprising:
- a first process of either imperfectly combusting or thermally decomposing a hydrocarbon fuel in a reactor, thereby producing a high-temperature gas flow containing fullerenes and soot;
a second process of collecting a mixture of the fullerenes and the soot from the gas flow containing the fullerenes and the soot using a filtering unit, said filtering unit including a heat-resistant filtering member made of either one of a porous ceramic material and a porous metal material as a raw material; and
a third process of collecting the fullerenes from the mixture.

Abstract
A hydrocarbon fuel is either imperfectly combusted or thermally decomposed in a reactor 11, thereby producing a high-temperature gas flow containing fullerenes and soot. A mixture of the fullerenes and soot is collected from the gas flow using a filtering unit 12 which includes a heat-resistant filtering member made of either a porous ceramic material or a porous metal material. The fullerenes are collected from the mixture by usual means. These processes according to the method of the present invention make it possible to produce a large amount of fullerenes.
