発明の名称 (英語) Highly efficient process for producing carbon nanostructure through raw material blasting and apparatus therefor
発明の概要(英語) A process for producing a carbon nanostructure in which a carbon nanostructure is produced with high efficiency while reducing the occurrence of tar-like by-products; and an apparatus therefor.
There is provided apparatus (2) for highly efficient carbon nanostructure production through raw material blasting, including reaction pipe (4) having catalyst body (12) disposed thereinside; heater (6) for heating the vicinity of the catalyst body (12) up to a temperature zone for formation of the carbon nanostructure (14); source gas supply pipe (8) for introducing source gas into the reaction pipe (4), with front end (8a) of the source gas supply pipe disposed in the vicinity of the catalyst body (12); and preheater (9) for preheating the source gas supply pipe (8) up to a temperature zone at which no tar-like products are formed from the source gas.
As in the source gas supply pipe no tar-like products are formed and as over an intermediate temperature the source gas is blasted at a breath to the catalyst body, the reaction probability would be increased to thereby increase the production yield of carbon nanostructure.
As most of the source gas is consumed, formation of tar-like substances is avoided in the reaction pipe (4) as well.
