摘要

本文采用1％Sr/La_2O_3-Ag-YSZ氧泵型催化膜反应器进行了甲烷氧化偶联反应研究。比较了不同制备方法的催化膜的反应性能

结果发现浸涂法(Ag-YSZ管随旋转轴转动涂制)制备的膜性能最佳。研究了操作条件对甲烷氧化偶联反应的影响。研究证明

传递氧与气相氧同时进料是一种较好的反应方式。结果表明

利用该反应器不仅可以简化分离过程

而且还可得到更高的C_2烃选择性。

Abstract

The 1% Sr/La2O3-Ag-YSZ catalytic membrane reactor with oxygen pumping type was applied to the oxidative coupling of methane (OCM). The preparation methods of the catalytic membrane were studied. The synthetic membrane prepared via impregnation 3 method was the most effective. The effects of transported oxygen flux

temperature

feed CH4 concentration

residence time on the reactivity of the catalytic membrane were investigated. Transported and premixed oxygen fed simultaneously was a good reaction mode. The results showed that not only the separation process could be simplified

but also higher catalytic activity and C2 - selectivity could be obtained.
