Oxidative Dimerization of Methane on Alkali Chloride Promoted Co3O4
TLDR
In this article, the optimum temperature at which C 2 -product yields were maximum was found when the promoter was changed from Li to Cs through group IA alkali metal chlorides.Abstract:
Oxidative dimerization of CH 4 has been studied using Co 3 O 4 catalysts promoted with chlorides of Li, Na, K and Cs. Chemical modification of Co 3 O 4 - LiCl catalyst at the reaction conditions was evidenced by ESR spectroscopy. A decrease in the optimum temperature, at which C 2 - product yields were maximum, was noticed when the promoter was changed from Li to Cs through group IA alkali metal chlorides.read more
