Noting the extensive application of minerals in catalysts and the urgent solution to address the global greenhouse problem caused by the too fast release of CO2, TiO2-attapulgite (ATP) was prepared by using a sol-gel method, on which Ni-Ru catalyst was loaded through impregnation for CO2 methanation. Performances of the samples with different contents of Ru and Ni were compared, while the influence of CO2 intake rate was especially studied and the reaction mechanism was explored by using in-situ IR spectroscopy. It was found that the bimetallic catalyst had excellent low temperature activities, whereas the effect of Ru was more pronounced. Among the catalysts prepared, 5Ni-1Ru-TiO2-ATP has the best catalytic effect, with the CO2 conversion rate reaching 47.9% at 350℃ and the highest (59.6%) at 400℃. Compared with the catalyst without Ru prepared under the same conditions, the conversion rate at 350℃ was increased by 31.8%, and at 400℃ by 26.5%. Excessive intake rate leads to insufficient gas-solid contact and poor catalytic effect. The composite catalyst followed a reaction path with CO* radicals as the intermediate.
