摘要：

Silica supported K2MoO4 and potassium-promoted MoO3 were used as catalysts for the partial oxidation of ethane in fix-bed continuous-flow reactor at 770-823 K using N2O as oxidant. The main products of the oxidation reaction were ethylene, acetaldehyde, CO and CO2. Addition of various compounds of potassium to the MoO3/SiO2 greatly enhanced the conversion of ethane and influenced the product distribution. The highest rate and selectivity for acetaldehyde formation was found on a K2MoO4/SiO2 catalyst.
