Abstract[English]
The present disclosure relates to an apparatus for producing high purity carbon nanotubes (CNTs) and related carbon allotropes and carbon nanomaterials with low metallic content. Moreover, this apparatus disclosed herein lends additional purification to such materials by the removal of amorphous carbon or other coke from the final material. In some embodiments, an apparatus for cleaning carbon nanomaterials includes a steam generation unit configured to provide steam via a gas line at a flow rate of about 0.001 L/min to about 10 L/min. The apparatus further includes a gas supply unit configured to provide a process gas to the gas line at a flow rate of about 0.001 L/min to about 15 L/min. The apparatus further comprises a purification/reaction unit including a reaction vessel. The apparatus further includes an exhaust gas cleaning unit.[French]
La présente divulgation concerne un appareil de production de nanotubes de carbone de haute pureté (CNT) et d'allotropes de carbone associés et de nanomatériaux de carbone à faible teneur métallique. De plus, cet appareil selon l'invention confère une purification supplémentaire à de tels matériaux par élimination du carbone amorphe ou d'un autre coke du matériau final. Dans certains modes de réalisation, un appareil de nettoyage de nanomatériaux de carbone comprend une unité de génération de vapeur conçue pour fournir de la vapeur par l'intermédiaire d'une conduite de gaz à un débit d'environ 0,001 L/min à environ 10 L/min. L'appareil comprend en outre une unité d'alimentation en gaz conçue pour fournir un gaz de traitement à la conduite de gaz à un débit d'environ 0,001 L/min à environ 15 L/min. L'appareil comprend en outre une unité de purification/réaction comprenant un récipient de réaction. L'appareil comprend en outre une unité de nettoyage de gaz d'échappement.
