    • A subject of the present invention is a process for producing carbon nanotubes, the process comprising: a) the synthesis of alcohol(s) by fermentation of at least one vegetable matter and optionally the purification of the product obtained; b) the dehydration of the alcohol or alcohols obtained in a) in order to produce, in a first reactor, a mixture of alkene(s) and water and optionally the purification of the product obtained; c) the introduction, in particular the introduction into a fluidized bed, in a second reactor, of a powdery catalyst at a temperature ranging from 450 to 850° C., this catalyst comprising at least one catalytic metal supported by an inert solid substrate, the grains of catalyst having a d50 of less than 300 μm; d) bringing the alkene produced in b) into contact with the powdery catalyst of stage c), optionally in a fluidized bed, in order to form carbon nanotubes and hydrogen on the surface of said catalyst by catalytic decomposition of said alkene; e) the recovery of the carbon nanotubes produced in d). 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.
    • 本发明的主题是一种生产碳纳米管的方法,该方法包括:a)通过至少一种植物物质的发酵和任选的所得产物的纯化来合成醇; b)在a)中获得的醇或醇的脱水,以便在第一反应器中产生烯烃和水的混合物,并任选地纯化获得的产物; c)引入,特别是在第二反应器中引入粉末状催化剂在450-850℃的温度下引入流化床,该催化剂包含至少一种由惰性固体基质负载的催化金属, d50小于300μm的催化剂颗粒; d)使b)中产生的烯烃与阶段c)的粉末催化剂任选地在流化床中接触,以便通过所述烯烃的催化分解在所述催化剂的表面上形成碳纳米管和氢; e)在d)中生产的碳纳米管的回收。 本发明还涉及能够根据上述方法获得的纳米管,其可有利地用于所有已知的碳纳米管应用领域。
