Oxidative dimerisation of methane on supported palladium oxide catalysts
TLDR
In this article, the authors used supported palladium oxide catalysts to convert CH4 to C2H6, CO, CO 2, CO2, H2 and H2O at temperatures below 400 °C.Abstract:
Supported palladium oxide catalysts are able to convert CH4 to C2H6, CO, CO2, H2 and H2O at temperatures ⩾315 °C. Catalysts did not show any support effect when TiO2, Al2O3, ZrO2, La2O3 and MgO were used as supports. With sequential O2 pulsing the catalyst showed long term activity when used at temperatures below 400 °C. Addition of Pt increased selectivity whereas with Ga it decreased. Results indicate participation of lattice O2 from catalyst in the reaction pathway.read more

Low temperature oxidative dehydrogenation of ethane over catalysts based on group VIII metals
TL;DR: In this article, the authors compared the catalytic properties of unsupported Fe, Co and Ni catalysts in the oxidative dehydrogenation of ethane (ODHE) at low temperature and found that the selectivity towards ethylene is found to be ca. 60% at low conversion.

V. Ducarme,A. Thaib,G. A. Martin +2 more
TL;DR: In this paper, the authors examined the effect of group VIII metals on the selective oxidation of ethane and showed that Pd leads mainly to total oxidation with Ni, surprisingly, is active and selective for the oxidative dehydrogenation of the ethane.

Active and selective catalysts for the synthesis of C2H4 and C2H6 via oxidative coupling of methane
TL;DR: In this article, active and selective catalysts for oxidative coupling of methane were tested over many metal oxides (30 oxides) under the experimental conditions chosen (T = 973 K, PO2 = 0.4 kPa, PCH4 = 18.2 kPa and PHe = 82.7 kPa).

Gas phase coupling of methyl radicals during the catalytic partial oxidation of methane
TL;DR: In this article, a lower limit for the rate of gas-phase CH/sub 3/* radical formation over a lithium-promoted MgO catalysts has been determined and this result is compared with the overall rate of C/sub 2/H/sub 6/ formation.
