โœฆ Synopsis

The oxidative coupling of methane has been studied on a (SmLi02)0,(CaOMgO)0~2 catalyst by using two different modes of heating: a conventional oven and a microwave irradiation set-up. The C2 selectivity obtained with microwave heating was much higher than with conventional heating especially at low conversions. This difference could arise from the reduction of oxidation products (ethane, ethylene) in the gas phase under microwave irradiation.

A series of zirconia doped Li/MgO catalysts with a fixed amount of zirconia and varying concentrations of lithium was used for the oxidative coupling of methane. It was found that an increase in lithium concentration resulted in a decrease in initial activity, while the selectivity was not affected.
