processos para produzir nanofribras de carbono e/ou nanotubos de carbono, e para realizar pelo menos uma reação química na presença de um catalisador suportado, partículas de carbono, e, catalisador ou precursor de catalisador.

摘要

The invention is directed to a process for producing carbon nanofibres and/or carbon nanotubes, which process comprises pyrolysing a particulate cellulosic and/or carbohydrate substrate that has been impregnated with a compound of an element or elements, the metal or alloy, respectively, of which is capable of forming carbides, in a substantially oxygen free, volatile silicon compound containing atmosphere, optionally in the presence of a carbon compound.
