TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: The carbon nanotube containing composition is bake-processed before performing bead mill processing. The carbon nanotube containing composition obtained by separation and recovery method, is dipped in the solution containing two or more types of liquid, and liquid separation processing is performed to separate solution containing carbon nanotube as main component and solution containing components other than carbon nanotube. The carbon nanotube supports the metal catalyst to the support, and is obtained by contacting with a carbon containing compound at 500-1200degreesC. Preferred Property: The bead has diameter of 30-100 microns. Preferred Composition: The support is chosen from miso porous material which has silica, alumina, magnesia, titania, zeolite and silicon as a main component. The metal catalyst contains vanadium, molybdenum, iron, cobalt, nickel, palladium, platinum, rhodium, tungsten and copper. EXAMPLE - Carbon nanotube containing composition was prepared using solid catalyst of metal salt (ferrous acetate and cobaltous acetate tetrahydrate) supported by TS-1 (RTM: zeolite), and ceramic non-woven fabric consisting of alumina and silica. The carbon nanotube containing composition was dispersed in toluene and slurry (1000 g) of 5% solid content and viscosity of 50 mPa was obtained. The obtained slurry was bead mill processed using product made from zirconia as bead having average particle diameter of 50 microns in a bead mill apparatus, and then processed in a processing chamber with slurry supply speed of 140 g/minutes, rotor circumferential speed of 10 m/second and slurry circulation of 6 times in the chamber. The obtained carbon nanotube containing composition was added with water-toluene mixed solution, stirred for 5 minutes and maintained for 30 minutes. The upper layer containing support (toluene layer) as main component was separated and removed. The lower layer containing carbon nanotube (aqueous layer) as a main component, was collected, filtered and dried at 60degreesC in atmospheric condition. The carbon nanotube containing composition (1.14 g) was obtained. 93% of carbon nanotube was contained in the carbon nanotube containing composition. The purity of the carbon nanotube was 85 wt.%
