Abstract：

Sepiolite　was　used　as　support　for　ruthenium　catalyst.　Non-promoted　Ru/Sep　is　proved　to　be　effective　for　ammonia　synthesis.　The　catalyst　was　characterized　by　XRD,　XPS　and　nitrogen　adsorption　isotherms.　Ru　is　reduced　completely　and　is　present　in　few　oxidation　states　on　the　support.　Using　non-aqueous　solvent　instead　of　water　in　the　impregnation　process　on　basic　support,　the　Ru　dispersion　could　be　increased.　Chlorine-free　Ruthenium　catalyst　was　prepared　using　RuC13　by　washing　with　ammonia　solution.
