| Results from TGA/DTGA of the Mg-Mo2C/HY and K-Mo2C/HY catalysts after 5 h of reaction with 5% naphthalene in heptane are shown in Fig. 5 and Table 3. Comparison of the spectra in Figs. 4 and 5 shows a larger weight loss below150 ¡ãC for the used catalysts than the un-used catalysts. This means that besides water, some volatile hydrocarbons remained on the catalysts after reaction. |
