FIELD: chemical industry; methods of manufacture of the composites, catalytic agents, the materials for the gases storing.

SUBSTANCE: the invention is pertaining to the method of the selective manufacture of the ordered carbonic nanotubes in the boiling layer and may be used at the composites, catalytic agents, the materials for the gases storing. First manufacture the catalytic agent by deposition of the transition metal particles on the grains of the carrier in the "boiling bed" in the deposition reactor at the temperature of 200-300°C. The particles of the metal have the average size of 1-10 nanometers metered after the action of the temperature of 750°C. The grains of the catalytic agent contain 1-5 % of the mass particles of the metal. Fragments of metal also have the average size of 10-1000 μ. The carrier has the specific surface above 10 m²/g and is selected from the activated charcoal, silica, silicate, magnesium oxide or titanium oxide, zirconium oxide, zeolite oxide or the mixture of the grains of several of these materials. The ordered carbonic nanotubes are manufactured by decomposition of the gaseous source of carbon, for example, hydrocarbon, at its contact with at least of one solid catalytic agent. The decomposition is conducted in the "boiling" bed of the catalytic agent in the growth reactor at the temperature of 600-800°C. The invention allows to increase the output of the pure nanotubes with in advance calculated sizes.

EFFECT: the invention allows to increase the output of the pure nanotubes with in advance calculated sizes.
