METHOD FOR EXTRACTING CARBON NANOTUBES FROM DISPERSED CARBON-CATALYST COMPOSITE Russian patent published in 2017 - IPC B03D1/02 B03D1/04 B82B3/00 C01B31/02 

FIELD: chemistry.

SUBSTANCE: invention is designed to extract carbon nanotubes from a dispersed carbon-catalyst composite into a separate product, used in the production of sorbents, catalyst carriers, stationary chromatographic phases, composite materials and functional coatings. The method for extracting carbon nanotubes from dispersed carbon-catalyst composite consists in repulping the composite in water at a ratio of T: H=1:3-T:H=1:5 with intensive pulp mixing at a stirrer speed of 200-1000 rpm, pulp conditioning with the addition of reagents based on acetylene or higher aliphatic alcohols, flotation of carbon nanotubes in the foam product, washing carbon nanotubes with water, followed by decantation and drying at a temperature of 90-200°C.

EFFECT: increasing the efficiency and productivity of extracting carbon nanotubes from dispersed carbon-catalyst composite.
