Abstract：

A　new　kind　of　Ru　supported　on　sepiolite　catalyst　with　La　as　promoter　for　ammonia　synthesis　was　prepared.　The　effects　of　reaction　conditions　on　catalytic　activity　were　discussed.　The　result　shows　that　La　is　an　effective　promoter　for　sepiolite-supported　Ru　based　catalyst.　When　the　load　of　Ru　is　5%　(mass　fraction),　and　the　molar　ratio　of　La/Ru　is　1.5,　under　the　condition　of　10　MPa　450°C　20000　h-1,　the　ammonia　synthesis　rate　is　38.5　mmol　NH3·g-1·h-1.
