摘要：

A double layered catalyst bed of Sr/La2O3 followed by MoO3/SiO2 has been used to produce C2 hydrocarbons and formaldehyde from a CH4 /air mixture with a formaldehyde space time yield of 187 g (kg cat)-1 h-1, which is significantly higher than those yields obtained with single bed catalysts or with mechanically mixed catalyst bed at ambient pressure and 630-degrees-C.
