V. Tashjian et al., OXIDATIVE DIMERIZATION OF METHANE IN MOLTEN LI2CO3-NA2CO3 EUTECTIC SUPPORTED BY LITHIUM ALUMINATE AT 700-850-DEGREES-C, Applied catalysis. A, General, 108(2), 1994, pp. 157-169
Catalytic oxidation of methane was performed in molten Li2CO3-Na2CO3 i
mmobilized on lithium aluminate. Pellets of the solid support with spe
cific features were prepared and characterized. The evolution of the c
atalytic effect with temperature and the oxoacidity of the medium were
systematically analyzed. C2 yields and methane conversion increased s
ubstantially with temperature. The catalytic activity at 750-degrees-C
was correlated with the presence of peroxide species in basic media (
C2 yield about 10% and methane conversion 14%). The influence of the p
roportion of molten carbonate in the Li2CO3-Na2CO3/LiAlO2 system was a
lso examined.
