METHOD OF PRODUCING CARBON NANOTUBES
FIELD: chemistry. ^ SUBSTANCE: carbon nanotubes are obtained by bringing a mixture of methane and hydrogen into contact with a catalyst. The process is carried out at high temperature and catalyst and gas mixture contact time equal to 10-60 minutes. The catalyst used is magnesium cobaltate Mg[CoO2]2...

| description | FIELD: chemistry. ^ SUBSTANCE: carbon nanotubes are obtained by bringing a mixture of methane and hydrogen into contact with a catalyst. The process is carried out at high temperature and catalyst and gas mixture contact time equal to 10-60 minutes. The catalyst used is magnesium cobaltate Mg[CoO2]2. The catalyst and mixture of methane and hydrogen with methane content 80-95 vol. % and hydrogen content 5-20 vol. % are brought into contact at temperature 650-750C. ^ EFFECT: invention enables to obtain straight carbon nanotubes, provides high output of carbon nanotubes per unit mass of the catalyst with high efficiency, enables to obtain a product which is multi-layered and has homogeneity of fractons on the diameter of the tubes. ^ 1 dwg, 1 tbl, 6 ex
Изобретение относится к химической промышленности и нанотехнологии. Получают углеродные нанотрубки путем приведения в контакт смеси метана и водорода с катализатором. Процесс проводят при повышенной температуре и времени контактирования катализатора и смеси указанных газов 10-60 мин. В качестве катализатора используют кобальтат магния Mg[CoO2]2. Контактирование катализатора и смеси метана и водорода состава 80÷95% об. метана и 5÷20% об. водорода проводят при температуре 650÷750°С. Изобретение позволяет получать прямые углеродные нанотрубки, обеспечивает высокий выход углеродных нанотрубок на единицу массы катализатора при высокой производительности, обеспечивает получение продукта с высокой многослойностью и однородностью фракции по диаметру трубок. 1 ил., 1 табл. |
