Fluidised bed catalytic CVD for the large scale production of of multiwalled- carbon nanotubes.

摘要

We are conducting a research program based on supported CCVD with the goal to develop a large-scale and low cost production process for MWNTs. We present the results concerning the engineering research on CCVD fluidised bed reactor process. It will be proven that, with the choice of the appropriate catalyst, an adequate design of the reactor and a fine control of the parameters that regulate the operative conditions, the fluidised bed CCVD allows a selective largescale production (50 g for 2h run) of multiwalled carbon nanotubes. The experimental equipment and the different parameters that have been studied will be first described along with the process and morphological analysis that have been realised. We will then present the results obtained in terms of selectivity, yield and fluidisation quality. Finally a first characterization of the obtained material will be presented.
