不同催化剂在甲烷燃烧反应中的活性评价

Assessment for Activities of Different Catalysts in the Methane Combustion Reaction

为探究不同催化剂对甲烷燃烧效率的影响,本文分别利用负载型贵金属催化剂、钙钛矿型催化剂和六铝酸盐催化剂,在不同条件下催化甲烷燃烧反应,并进行催化活性评价。结果表明:负载型贵金属催化剂其La/Ce前驱体高于氯化物前驱体的催化燃烧性能;钙钛矿催化剂中Sr的燃烧活性最高;Mn代六铝酸盐催化剂活性高于Co代活性。

In order to explore the influence of different catalysts on combustion efficiency of Methane,the catalytic activities of catalysts,loaded noble metal catalyst,perovskite type catalyst and six aluminate catalyst,were evaluated by the combustion reaction of Methane under different conditions.The results showed that catalytic combustion performance of the loaded noble metal catalyst with La/Ce precursor was higher than that with chloride,the combustion performance of Sr was the highest in the perovskite catalysts and the activity of Mn substituted six aluminate catalyst was higher than the Co substitution.
