甲烷催化燃烧催化剂催化理论与应用研究进展

Research Progess of the Catalysts for Methane Catalytic Combustion in the Theory and Application

概述了甲烷催化燃烧催化剂的研究现状,从组成甲烷燃烧催化剂的3个部分(基体、活性组分、氧化物载体)分别加以论述。通过掺杂一些金属和金属氧化物,不但可以提高高活性贵金属催化剂的热分解温度,还可以提高高温催化剂(如钙钛矿和六铝酸盐材料等)的催化活性。最后简要综述了甲烷催化燃烧反应机理。

The recent research progress and developments of the catalysts for methane catalytic com -bustion were described. The catalysts for methane catalytic combustion which was composed in three parts（ base ,active constituent and oxide support） were also discussed. It is shown that ,the addition of metals and metal - oxides improves the thermal stability of noble metal catalysts and metal - oxide catalysts such as perovskites and hexaaluminates, and brings benefit to activity in methane catalytic combustion. Finally, the reaction mechanism for methane catalytic combustion was summarized simply.
