摘要: 甲烷氧化偶联反应在不同催化剂体系上动力学的研究各不相同,我们[1]已报道了La-Ba-O系复合氧化物催化剂对此反应的优良催化性能。本文则是对该催化剂上的甲烷氧化偶联反应的动力学进行初步探讨。

Abstract: The kinetic study on the oxidative coupling of methane over the La-Ba-Na-O catalyst showed that the formation rates of ethane and ethylene were nearly the first order with respect to the partial pressure of methane and zero order to that of oxygen, while the formation rate of carbon dioxide was nearly zero order and the first order with respect to the partial pressures of methane and oxygen, respectively. The reaction mechanism has been discussed on the basis of activation energies.
