発明の名称 (英語) Highly efficient process for producing carbon nanostructure through raw material blasting and apparatus tehrefor
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 for highly efficient carbon nanostructure production through raw material blasting, including reaction pipe having catalyst body disposed thereinside; heater for heating the vicinity of the catalyst body up to a temperature zone for formation of the carbon nanostructure ; source gas supply pipe for introducing source gas into the reaction pipe, with front end of the source gas supply pipe disposed in the vicinity of the catalyst body ; and preheater for preheating the source gas supply pipe 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 probabilitywould 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 as well.
