| Abstract: | The reactions of methane decomposition to deposited carbon, CO 2 reforming of methane to deposited carbon and CO 2 elimination of carbon over hexaaluminate LaNiAl 11 O 19 catalyst have been studied as a function of the appearance, sources, kinds and activities of deposited carbon by TEM, XPS, TGA, TPR CO 2 techniques. The results showed that methane exhibited rather high decomposition activity and carbide carbon and graphitic carbon were detected. However, the activity of CO 2 decomposition to deposited carbon was lower, but its activity of eliminating carbon was higher. |
