Claims (6)

1. Катализатор синтеза аммиака, включающий в качестве каталитически активного металла рутений, нанесенный на окись магния, и промотор, отличающийся тем, что окись магния имеет удельную поверхность, по меньшей мере, 40 м2/г, концентрация рутения составляет между 3 и 20 мас.% и содержание промотора составляет между 0,2 и 0,5 молей на моль рутения, причем промотор представляет собой щелочные металлы, щелочноземельные металлы, лантаниды и их смеси.1. The catalyst for the synthesis of ammonia, comprising as a catalytically active metal ruthenium supported on magnesium oxide, and a promoter, characterized in that the magnesium oxide has a specific surface area of at least 40 m 2 / g, the concentration of ruthenium is between 3 and 20 wt. % and the content of the promoter is between 0.2 and 0.5 moles per mole of ruthenium, the promoter being alkali metals, alkaline earth metals, lanthanides and mixtures thereof. 2. Катализатор синтеза аммиака по п.1, отличающийся тем, что в качестве промоторов включают цезий и/или барий.2. The ammonia synthesis catalyst according to claim 1, characterized in that cesium and / or barium are included as promoters. 3.
