Abstract
A method for preparing a catalyst for conversion of methane to higher hydrocarbons, discloses the steps of forming a mixture of a manganese aqueous solution and an oxidative agent aqueous solution in an inorganic oxide support material; varying a pH value of the mixture between acidic and basic values to obtain a precipitate of manganese oxide; drying the manganese oxide precipitate; impregnating the dried manganese oxide precipitate with a promoter to obtain an impregnated solid; drying the impregnated solid; and calcining the impregnated solid until a surface atomic ratio of promoter to manganese is at least 5. The catalyst so acquired may be contacted with a methane gas to obtain stable conversion values over extended reaction times.
