摘　　要：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). Mainly growing on quartz wool or wall of reactor, the bulk CNTs were obtained. 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 CH 4 on the Ni particles. After transported out of the catalyst zone by blowing of feedgas, CNTs adhered to quartz wool or the wall of reactor. Predominately, the other way was that firstly syngas was produced from POM reaction and then CNTs grew from disproportionation of CO in presence of hydrogen. A little remaining oxygen in effluent could remove the other morphologic carbon, so CNTs were easily opened and purified at the same time of growth. This research maybe arouse us to assemble the continuous process of POM and preparation of CNTs. CNTs were applied to be negative materials for lithium battery. The reversible electrical capacity of simulative lithium battery can be increased ca. 20% with adding 10%(in mass fraction) carbon nanotubes into natural graphite.
