Carbon nanotube prepared in the atmosphere of partial oxidation of methane

In the present work, Ni-Ce catalyst was used for the preparation of carbon nanotubes (CNTs) in the atmosphere of partial oxidation of methane (POM). M ainly growing on quartz wool or wall of reactor, the bulk CNTs were obtaine d. Probably CNTs were synthesized by two routes due to the typical reaction conditions of POM, One was that CNTs were produced from the decomposition of CH4 on the Ni particles. After transported out of the catalyst zone by b lowing of feedgas, CNTs adhered to quartz wool or the wall of reactor, Pred ominately, the other way was that. firstly syngas was produced from POM rea ction and then CNTs grew from disproportionation of CO in presence of hydro gen. A little remaining oxygen in effluent could remove the other morpholog ic carbon, so CNTs were easily opened and purified at the same time of grow th, This research maybe arouse us to assemble the continuous process of POM and preparation of CNTs, CNTs were applied to be negative materials for li thium battery. The reversible electrical capacity of simulative lithium bat tery can be increased ca, 20% with adding 10% (in mass fraction) carbon nan otubes into natural graphite.
