摘　　要：Reaction chemistry of the OCM reaction on W-Mn/SiO2 catalyst has been reviewed in thisaccount. Initial activity and selectivity, stability in a long-term reaction, reaction at elevated pressures anda modelling test in a stainless-steel fluidized-bed reactor show that W-Mn/SiO2 has promising performancefor the development of an OCM process that directly produces ethylene from natural gas. A study onsurface catalytic reaction kinetics and used catalyst structure characterization revealed a possible reasonwhy C2 and COx selectivity changed during the long-term reaction. Further improvement of the catalystcomposition and preparation method should be a future direction of study on OCM reaction over W-Mn/SiO2 catalyst. 关键词：甲烷氧化偶连反应负载型催化剂锰钨二氧化硅
