20080213138 | Production Method and Production Device for Carbon Nano Structure - A material gas and a catalyst are introduced through a material supplying tube path and a catalyst supplying tube path together with a carrier gas into a reactor equipped on its outer periphery with a heat applicator for thermally decomposing the material gas.
