METHOD AND APPARATUS FOR PREPARING FULLERENE

摘要

PROBLEM TO BE SOLVED: To provide a method of preparing fullerene by which the fullerene is efficiently separated and recovered from a large quantity of a soot like material produced in the mass production of fullerene. SOLUTION: A hydrocarbon raw material is incompletely combusted or thermally decomposed to produce a soot-like material-containing gas stream containing fullerene, a polycyclic aromatic compound and a carbon-based high polymer component. The high temperature soot-like material-containing gas stream is passed through a heat resistant filter 20 to separate and remove a vaporized material consisting essentially of the polycyclic aromatic compound to obtain the soot-like material-containing fullerene.
