다국어 초록 (Multilingual Abstract)
In this study, catalytic activity and selectivity to C₂ hydrocarbons on oxidative coupling of methane over Ca-Ni-K oxide catalysts were studied by varying the atomic ratio of the catalyst. In addition, effects of water as an additive reactants and the effect oxidative pretreatment of surface on the catalysts performance were investigated. It was established that, for the methane coupling reaction Ca₃NiK_(0.1)OX proved to be a better catalyst in catalytic activity, Ca₄NiK_(0.1)OX was best among the catalysts tested. As far as hydrocarbon selectivity is concerned water as an additive reactant enhanced hydrocarbon selectivity and the reaction conversion simultaneously, and it was found that oxidation state of catalyst surface is an important factor for catalytic activity and selectivity of this reaction.
