Preparation of carbon nanotubes comprises synthesis of an alcohol by fermentation of at least a vegetable material; dehydratation of the alcohol, in primary reactor, a mixture of alkene and water; placing a catalyst powder at 450-850[deg] C, in a fluidized bed, in a second reactor, where the catalyst comprises at least a supported catalytic metal by inert solid substrate; contacting the alkene product with the catalyst powder in fluidized bed to form the carbon nanotubes and hydrogen by catalytic decomposition of the alkene, on the catalyst surface; and recovering the carbon nanotubes product.
