CARBON NANOTUBE SYNTHESIS APPARATUS HAVING IMPELLER TO CONTROL DENSITY OF CARBON NANOTUBES

摘要

The present invention relates to an apparatus for synthesizing carbon nanotubes having an impeller for controlling density of carbon nanotubes. Instead of improving density of carbon nanotubes through multiple post-steps such as mixing, molding and drying in methods according to the related art, the present invention provides an apparatus for synthesizing carbon nanotubes while controlling density of carbon nanotubes by improving the shape of an impeller spraying a reaction gas onto a catalyst during the process for synthesizing carbon nanotubes in an apparatus for synthesizing carbon nanotubes. The apparatus for synthesizing carbon nanotubes comprises: a reaction chamber providing a space for forming carbon nanotubes; a catalyst supplying section for supplying a catalyst into the reaction chamber; an impeller having at least one rotating blade spraying a reaction gas onto the catalyst; and a reaction gas supplying tube for supplying the reaction gas into the impeller, wherein the rotating blade has a gas transfer line therein for receiving the reaction gas, a gas supplying hole is extended at the outer circumferential surface of the reaction gas supplying pipe for supplying the reaction gas to the gas transfer line, and the gas transfer line is formed at a position spaced apart from the linear line extending from the gas supplying hole horizontally.
