METHOD OF OBTAINING LONG CARBON NANOPIPES AND DEVICE FOR THEREOF REALISATION Russian patent published in 2013 - IPC C01B31/02 B82B3/00 B82Y30/00 

FIELD: chemistry.

SUBSTANCE: invention can be applied in production of highly strong complex carbon threads and composition materials for auto- and/or aircraft construction. Carbon-containing component, activator and precursor of catalyst of growing carbon nanopipes are introduced in flow of gas-carrier through device for their introduction with formation of mixture. Obtained mixture is passed through vertical reactor with work chamber, heated to 1000 to 1200 °C by device for its heating. Formed nanopipes are brought out into product receiver. Mixture is supplied into reactor from bottom to top with linear speed from 50 to 130 mm/s. When said work temperature is reached in mixture flow, its linear speed is reduced to 4-10 mm/s, and before output from reactor is increased to 30-130 mm/s. Chamber of reactor is made from three successive sections - lower input 16, middle 17 and upper output 18. Diameter of section 16 constitutes from 1/3 to 1/5 from section 17 diameter, and diameter of section 18 constitutes from 1/3 to 1/4 of section 17 diameter. Output of device for mixture supply into work chamber is connected with input of lower input section 16.

EFFECT: plaints of long multi-layer and well-oriented nanopipes are obtained, stability of continuous process is ensured.
