低温甲烷氧化偶联稀土氧化物催化剂的研究进展
|
摘要
在甲烷氧化偶联制乙烯(Oxidative coupling of methane,OCM)反应中,在700℃以下具有显著催化活性的催化剂称为低温催化剂。从低温催化剂的组成、制备方法及催化性能等方面综述了近年来Re_xO_y(Re=La、Y、Sm和Nd等稀土元素)稀土氧化物类低温催化剂的研究进展。对于具有潜在工业化应用前景的催化剂进行了简要分析。
The catalysts having considerable catalytic activation for oxidative coupling of methane(OCM) reaction at 700℃ or lower were called low temperature catalysts.Some research results about rare earth oxide(Re_xO_y) on composition,preparation and catalytic performance were reviewed for the last several years.Meanwhile,the potential commercial application of catalysts was also analyzed.
