本文详细地报导了氯化锂在甲烷氧化偶联制乙烯过程中的助催化作用。大量实验结果证明,不仅在单一金属氧化物中,就是在多种金属氧化物的混合物以及在有载体存在下的金属氧化物中,只要加入氯化锂,就可明显的提高乙烯的选择性和收率,尤其是与硼酸、磷酸以及 LQ 载体配合使用时效果更好,使乙烯的选择性达80%,乙烯的收率达30%,而且甲烷的分压可提高到0.4atm。
This paper reports in detail the cocatalytic activity of lithium chloride in the ethylene oxidation of methane. Numerous experimental results show that not only in a single metal oxide, but also in a mixture of a plurality of metal oxides and a metal oxide in the presence of a carrier, the addition of lithium chloride significantly increases the selectivity of ethylene and The yield, especially when used in combination with boric acid, phosphoric acid, and LQ support, provides better ethylene selectivity of 80%, ethylene yield of 30%, and methane partial pressure of up to 0.4 atm.
