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.

基于黏土矿物在催化剂制品中的广泛应用和因CO2增长过快造成的全球温室效应,通过溶胶凝胶法在凹凸棒石(ATP)表面负载TiO2并以其为载体,采用浸渍法制备了用于CO2甲烷化的Ni-Ru/TiO2-ATP催化剂。比较Ru和Ni负载量对催化性能的影响,重点考察了反应温度和空速对甲烷化过程的影响,并采用原位红外测试技术进一步揭示了其反应机理。结果表明:双金属催化剂具有优异的低温催化活性。制备的催化剂中5Ni-1Ru-TiO2-ATP的催化效果最佳,在350℃时CO2转化率达到47.9%,在400℃时转化率最高,为59.6%。比相同条件下制备的不含Ru的催化剂在350℃时的转化率提高31.8%,在400℃时提高26.5%。进气速率过大会导致气固相接触不充分,催化效果变差。原位红外分析发现该多元复合催化剂遵循一种以CO*基团为中间体的反应机理。

基于黏土矿物在催化剂制品中的广泛应用和因CO2增长过快造成的全球温室效应,通过溶胶凝胶法在凹凸棒石(ATP)表面负载TiO2并以其为载体,采用浸渍法制备了用于CO2甲烷化的Ni-Ru/TiO2-ATP催化剂。比较Ru和Ni负载量对催化性能的影响,重点考察了反应温度和空速对甲烷化过程的影响,并采用原位红外测试技术进一步揭示了其反应机理。结果表明:双金属催化剂具有优异的低温催化活性。制备的催化剂中5Ni-1Ru-TiO2-ATP的催化效果最佳,在350℃时CO2转化率达到47.9%,在400℃时转化率最高,为59.6%。比相同条件下制备的不含Ru的催化剂在350℃时的转化率提高31.8%,在400℃时提高26.5%。进气速率过大会导致气固相接触不充分,催化效果变差。原位红外分析发现该多元复合催化剂遵循一种以CO*基团为中间体的反应机理。

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.
