Abstract:
1. An industrial process for fabricating carbon nanotubes (CNTs), comprising synthesis of the carbon nanotubes by decomposing a carbon source brought into contact, in a fluidized-bed reactor at a reaction temperature between 500° C. and 1500° C. with a catalyst in the form of substrate grains covered with a metal, the nanotubes produced being recovered, in which 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 at the reaction temperature for synthesizing the CNTs, and discharge taking place beneath the reactor via an outlet of the reactor; wherein it comprises the following steps:
