摘要:
This invention relates to a method for producing carbon nanotubes in a dispersed state. The method comprises a stage whereby polymerization is carried out from at least one so-called monomer of interest, in the presence of a catalytic system. The catalytic system comprises a co-catalyst/catalyst catalytic couple that is supported by a catalyst carrier, which corresponds to said carbon nanotubes. The invention also relates to composite materials obtained by said method, and to a catalytic system for implementing said method. The invention further relates to the use of the inventive method and products in a field of polymers, especially that of nanotechnologies.

The present invention relates to a catalyst system for the selective conversion of hydrocarbons into multi-walled carbon nanotubes and hydrogen comprising a compound of the formula: (Ni,Co)FeyOz(Al2O3)w wherein ‘y’ represents the molar fraction of Fe relative to Co and Ni and wherein 0.11≦y≦9.0, 1.12≦z≦14.5, and 1.5≦w≦64.
摘要:
The present invention relates to a method for synthesising a catalyst with a view to the production of multi-wall nanotubes comprising the following stages: mixing an Al(OH)3 powder having a particle size lower than 80 μm with an aqueous solution of an iron and cobalt salt, the whole forming a paste; drying said paste until a powder with a moisture level lower than 5% by weight is obtained; selecting the particle-size fraction that is lower than 70 μm.

The present invention relates to a catalytic composition for the synthesis of carbon nanotubes, comprising an active catalyst and a catalytic support, the active catalyst comprising a mixture of iron and cobalt in any oxidation form and the catalytic support comprising exfoliated vermiculite.
摘要:
The present invention is related to a continuous method for the functionalization of a pulverulent product in a plasma reactor comprising the steps of:—generating a plasma in a vertical reactor;—bringing the pulverulent product in contact with said plasma by letting said particles fall by gravity from top to bottom trough said reactor. The present invention also discloses an instalation for performing the functionalization method.
