摘要:
The present invention is related to a continuous method for the functionalization of a pulverulent product in a plasma reactor comprising the steps of: - generating a plasma in a vertical reactor; - bringing the pulverulent product in contact with said plasma by letting said particles fall by gravity from top to bottom trough said reactor. The present invention also discloses an installation for performing the functionalization method.
摘要:
Catalyst composition comprises a mixture of iron and cobalt in any form of oxidation and catalyst support comprising exfoliated vermiculite. Independent claims are included for: (1) synthesizing the catalyst composition, comprising exfoliating the vermiculite by treating vermiculite ore at above 800[deg] C, contacting the exfoliated vermiculite with a solution of a salt of cobalt and iron, and calcining the contacted vermiculite at above 350[deg] C; and (2) synthesizing carbon nanotubes by decomposition of hydrocarbon gas on the catalyst composition, comprising conditioning the catalyst composition in an inert atmosphere, and contacting the catalyst composition with a source of carbon gas at 600-800[deg] C for at least 5 minutes.
