Reaction chemistry of the OCM reaction on W-Mn/SiO2 catalyst has been reviewed in this account. Initial activity and selectivity, stability in a long-term reaction, reaction at elevated pressures and a modelling test in a stainless-steel fluidized-bed reactor show that W-Mn/SiO2 has promising performance for the development of an OCM process that directly produces ethylene from natural gas. A study on surface catalytic reaction kinetics and used catalyst structure characterization revealed a possible reason why C2 and COX selectivity changed during the long-term reaction. Further improvement of the catalyst composition and preparation method should be a future direction of study on OCM reaction over W-Mn/SiO2 catalyst.
