Effect of Lithium Chloride (Licl) Dopant on The Performance of Catalysts for the Oxidative Coupling of Methane
The present study reports effects of lithium chloride (LiCl) doping on MgO, La2O3, SnO2, CaO and ZnO catalysts. All the catalysts were prepared by the impregnation method. The catalysts were tested at reaction temperature of 775oC. The feed flow rate of methane, oxygen and nitrogen was carried...

| description | The present study reports effects of lithium
chloride (LiCl) doping on MgO, La2O3, SnO2, CaO and
ZnO catalysts. All the catalysts were prepared by the
impregnation method. The catalysts were tested at
reaction temperature of 775oC. The feed flow rate of
methane, oxygen and nitrogen was carried out in the
ratio of 3:1:2 giving a weight hourly space velocity
(WHSV) of 0.375 g.s/cm3. La2O3 showed the highest
C2+ selectivity among the undoped catalysts. All the
catalysts were doped with LiCl to compare their
methane conversion, selectivity and product yield. The
2.0 mol% LiCl doped into La2O3 was the best catalyst
formulation having achieved 46.7% of C2+ selectivity
with CH4 conversion of 29.0% and the increase in
selectivity was attributed to the presence of chlorine.
Hydrogen production was more pronounced for MgO
based catalysts and believed to be generated by surfacecatalyzed
reactions. |
