- W67432890 abstract "Magnesium and calcium oxides promoted with small amounts of lithium, sodium or potassium have been shown to be very active and selective for the production of higher hydrocarbons, particularly ethane and ethylene from methane. Typical methane conversions are 20 to 30% at a net selectivity to C/sub 2/'s of better than 60%. Small amounts of C/sub 3/ and C/sub 4/ hydrocarbons are also produced with the remaining products being CO/sub 2/ and CO. Temperature studies indicate that carbon oxide selectivity drops as the temperature is increased from 600 to 730/sup 0/C then rises again as the temperature is further increased. Order dependence measurements show the reaction to be zero order in O/sub 2/ and 0.7 order in CH/sub 4/ with an apparent activation energy of 175 kJ/mole. The mechanism appears to be activation of methane at the catalyst surface with subsequent release of methyl radicals into the gas phase. Methyl radicals then combine or react with other hydrocarbons. Simulation of the proposed reaction sequence has produced a good fit to experimental data." @default.
