The invention relates to a method for filling a receptacle () with carbon nanotubes from another receptacle () whereby the CNTs are passed from one receptacle to the other by means of a coupling () comprising a double-valve device (), each valve being coupled to one of the receptacles, the valves () closing independently and tightly and being openable only when they are coupled to one another.

Method for safe filling with carbon nanotubes, filling system and industrial plant employing this method

An industrial process and an apparatus for fabricating carbon nanotubes (CNTs) is provided, comprising synthesis of the carbon nanotubes by decomposing a carbon source brought into contact, in a fluidized-bed reactor, whereby the carbon nanotubes synthesized in the reactor and fixed onto the grains of catalytic substrate in the form of an entangled three-dimensional network, forming agglomerates constituting the CNT powder, are recovered sequentially by discharging them while hot, that is to say at the reaction temperature for synthesizing the CNTs, at the foot of the reactor, the sequence in which the discharges are carried out corresponding to the frequency of filling of the reactor.

Process for fabricating carbon nanotubes and apparatus for implementing the process

A subject of the present invention is a process for producing carbon nanotubes, the process comprising: The invention also relates to nanotubes capable of being obtained according to the abovementioned process, which can be advantageously used in all the known fields of application of carbon nanotubes.

Process for producing carbon nanotubes from renewable raw materials

The present invention relates to a process for preparing CNTs by bringing a carbon source into contact with a multivalent metal and/or metal-oxide-based catalyst deposited on an inorganic substrate having a BET specific surface area of greater than 50 m/g. The CNTs obtained may be used as agents for improving the mechanical and electrical conductivity properties in polymeric compositions.

Method for synthesis of carbon nanotubes

The invention relates to a method for synthesis of carbon nanotubes of the highest carbon purity by the process of vapour phase chemical deposition. The nanotubes produced can be used to advantage in all know applications of carbon nanotubes.
