Abstract:
1. A production apparatus for at least one of carbon nanotube and carbon nanofiber production comprising: a reactor to which a material and a carrier gas are supplied and which is configured to allow the material to react to synthesize at least one of a carbon nanotube and a carbon nanofiber by a gas phase flow reaction method; a discharge pipe through which the carrier gas and a product resulting from the reaction of the material and containing the at least one of a carbon nanotube and a carbon nanofiber are discharged from the reactor; a filter provided in the discharge pipe to catch the at least one of a carbon nanotube and a carbon nanofiber; suction means provided in a portion of the discharge pipe located downstream of the filter to suck the carrier gas in the discharge pipe; a pressure sensor provided in a portion of the discharge pipe located between the reactor and the filter to detect the pressure in said portion of the discharge pipe; and a control section configured to control the suction means so that a pressure sensed by the pressure sensor has a preset value.
