摘要
本文通过IR.XRD对Li_2CD_3/CaO系列催化剂进行了相组成测试及分析。与催化剂的催化效果进行关联的结果表明:高度分散的Li_2CO_3有利于C_2烃的生成,Li_2CO_3集结成较大的晶块时,C_2烃收率下降。提出了氧化偶联活性中心的形成过程。
The phase composition of Li_2CO_3/CaO series catalyst for the oxidative coupling of methane was tested and analysed by IR、XRD measurments. The results connected with the catalytic effect of catalyst show that high dispersed Li_2CO_3 is beneficial to the formation of C_2 hydrocarbon. When Li_2CO_3 crystal sizw increased, the yield of C_2 hydrocarbon was decreased. The formation course of active center of the oxdative coupling of methane was put forward.
