摘要

从常用载体γ-Al₂O₃和稀土氧化物的稳定性出发,详细阐述了有机废气尤其是轻质烷烃的催化燃烧催化剂的水热稳定性调变方法,并对活性金属的金属比例、核壳结构等进行总结,对催化剂水热稳定性的提高方法进行了综述。

Abstract

The hydrothermal stability of the catalysts for combustion of organic waste gas,especially light alkanes,is discussed.The modulation methods to enhance the stability of the common supports γ-Al₂O₃ and rare earth oxides are described,the metal proportions and core-shell structure of the active components are summarized,and the improvement of hydrothermal stability of catalysts is reviewed.
