Catalyst for conversion of methane to ethylene, preparation thereof, and process for manufacturing ethylene using said catalyst

The present invention relates to a new catalyst for converting methane into ethane, preparation thereof, and process for manufacturing ethylene using said catalyst. The conversion reaction catalyst in the present invention is employed in converting directly methane or methane-containing gas in the presence of the above catalyst with the following general formula (1). Ma.Pc.D/S (1) Where, M is a metal cluster or metal complex compound selected from the group of VIII, VII and VI series; S is an inorganic carrier; P is a promoter of phosphorus compound; D is a cobalt compound. And "a" is weight percentage of metal cluster or metal complex compound in catalyst, having a value of 0.01 to 10, "c" is weight percentage of promoter in catalyst, ranging from 1.0 to 35.0.
