Zusammenfassung:Manufacture of a fullerene comprises: (a) preparing a mixture including fullerene, polycyclic aromatic hydrocarbon, and a carbon polymeric component; (b) separating the mixture into a polycyclic aromatic hydrocarbon and a mixture of fullerene and carbon polymeric component; and (c) separating this mixture into fullerene and carbon polymeric component. Independent claims are also included for: (1) the separation of fullerenes where the temperature when subliming the polycyclic aromatic hydrocarbon is 100-800[deg]C and the pressure is 0.001-200000 Pa; and (2) the fullerenes obtained by firing and/or heat decomposing a hydrocarbon compound where the polycyclic aromatic hydrocarbon content is at most 1000 ppm.
