Title:
METHOD FOR PRODUCTION OF CARBON NANOTUBE
Document Type and Number:
WIPO Patent Application WO/2008/029927
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a carbon nanotube production method which can produce a
carbon nanotube on a large scale and at low cost. [MEANS FOR SOLVING PROBLEMS] A
catalyst supported on a substrate is heated to a high temperature by heating the
substrate. A feed gas containing a carbon source is supplied onto the catalyst to
synthesize a carbon nanotube. The synthesized carbon nanotube is collected, and
subsequently the catalyst is subjected to a regeneration treatment. In this manner,
the substrate is used repeatedly. Since the catalyst is deteriorated, the regeneration
treatment of the catalyst is conduced at regular or irregular intervals during
the production process. The regeneration treatment of the catalyst involves
an oxidation treatment of the catalyst. After the oxidation treatment, a reducing
gas is supplied onto the surface of the catalyst. The catalyst is reduced by contacting
with the reducing gas. As for the substrate, a honeycomb can be used.
