摘要
天然气中的甲烷和乙烷可以同时在Ｎａ２ＷＯ４－Ｍｎ／ＳｉＯ２催化剂上得到活化生成乙烯。在甲烷转化率为２０％时，原料甲烷氧化偶联反应生成Ｃ２＋的选择性为～８０％，原料乙烷反应的转化率为～８５％，选择性为～７０％。
Methane and ethane in natural gas can be coactivated over Na_2 WO_4Mn/SiO_2 catalyst to produce ethylene. When methane conversion is kept at 20%, the C+2 selectivity of the OCM reaction can reach about 80%, and around 85% of the feed ethane can be converted with a selectivity of about 70%.
