Abstract
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.
