Abstract:
An improved process for preparing a catalyst having the formulaAaMmNnXxOowherein 0.25admixing metal compounds, at least one of which is an oxygen containing compound, and at least one solvent to form a mixture, removing the solvent from the mixture to obtain a catalyst precursor, and calcining the catalyst precursor to form said catalyst; wherein the improvement comprises:(A) admixing said metal compounds, at least one of which is an oxygen containing compound, and said at least one solvent to form a solution; (B) removing the solvent from said solution, by the application of heat and vacuum pressure to said solution, to obtain a catalyst precursor; and (C) calcining said catalyst precursor at a temperature from 350Â° C. to 850Â° C. under an inert atmosphere, wherein said inert atmopshere is not flowing over said catalyst precursor, to from said catalyst having the formula AaMmNnXxOowherein 0.25
