METHOD OF PRODUCTION OF FULLERENE Russian patent published in 2006 - IPC C01B31/02 

FIELD: atomic power; methods of utilization of substandard materials.

SUBSTANCE: the invention is pertaining to the field of atomic power, to the methods of utilization of substandard materials such as the reactor black lead and a solid fuel, in particular, to production of fullerene. The invention provides for preparation of a mixture from the solid fuel and the spent reactor black lead ground up to the size of the fraction of no more than 2 mm at their ratio from 1:2 to 1:10 accordingly. Intermix it up to production of the uniform mass. In addition introduce MgO,_{Al2О, SiO2,CaF2 andC20-28 in amountof 5 % from the total mass of the mixture. The prepared mixture feed to the reaction zone of the installation. Conduct the thermal sublimation first at the temperature of 1800÷2700°C with the subsequent temperature rise up to 3500-5000°C. The reprocess product is withdrawn to the ultracentrifuge for separation. The separated solid material is withdrawn for usage as the target product - fullerene. The gaseous phases are subjected to the bubbling process through the alkaline solution with the subsequent conservation of a deposit. The final treatment of the gas is conducted using the screen of Petrjanov's system. The invention allows to expand the source base of raw materials for production of fullerenes, allows to utilize sub-standard materials and to improve ecology.}

EFFECT: the invention ensures expansion of the source base of raw materials for production of fullerenes, utilization of sub-standard materials for the purpose and to improve ecology.
