Oxidative coupling of methane over doped Li/MgO catalysts
نویسندگان
چکیده
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. The life-time of Zr doped Li/MgO catalysts with a fixed concentration of ZrOz is a function of the lithium concentration. Previous results have shown that Li2Mg3Zr06 is active and selective but it is now shown to be instable under reaction conditions.

Effect of Additives on Lithium Doped Magnesium Oxide Catalysts Used in the Oxidative Coupling of Methane
It has been found that it is possible to improve the activity and stability for the oxidative coupling of methane of a Li/MgO catalyst by the addition of small amounts of the oxides of various transition and rare earth metals. A number of these additives, e.g. SnOZ, TiOz, Dy,O, and Tb407, caused little or no difference in the selectivity to C, products achieved with the resultant catalyst while...

The promoting effect of niobium in a Li/MgO catalyst for the oxidative coupling of methane (OCM) and for the oxidattve dehydrogenation of ethane (ODHE) has been studied in some detail. it has been found that a Li/Nb/MgO catalyst with 16 wt % niobium showed the highest activity for the C, production in the OCM reaction; the activity at 600 “C was ten times that of the Li/MgO catalyst at the same...
متن کاملMethyl Radicals in Oxidative Coupling of Methane Directly Confirmed by Synchrotron VUV Photoionization Mass Spectroscopy
Gas-phase methyl radicals have been long proposed as the key intermediate in catalytic oxidative coupling of methane, but the direct experimental evidence still lacks. Here, employing synchrotron VUV photoionization mass spectroscopy, we have directly observed the formation of gas-phase methyl radicals during oxidative coupling of methane catalyzed by Li/MgO catalysts. The concentration of gas-...

We present a study on the catalytic cycle responsible for coupling of methane by molecular oxygen over a lithium-doped magnesium oxide catalyst. To elucidate the mechanism by which methyl radicals are produced and the active sites are regenerated, geometries and energies of relevant reaction intermediates were determined using an ab initio embedded cluster model. Our results suggest a new mecha...
