摘要
本文考察了用于甲烷氧化偶联反应的Li-Ni-Y-O系复合氧化物催化剂的组成、制备条件以及各反应条件对反应活性的影响,考察了催化剂的稳定性,并利用XRD对此系列催化剂进行了结构表征。
The oxidative coupling of methane was studied over the Li-Ni-Y-O mixed oxide cata-lysts. The effects of the catalyst composition and preparation method and the reaction con-ditions on the activity of LiNi_(0.7)Y_(0.3)O_2 and the reaction products were examined. The C_2yield up to 22% at methane conversion of 40% was obtained. The XRD analysis indicatedthat the catalyst was composed of LiNiO_2 and LiYO_2, showing a synergetic effect on tehreaction.
