Abstract: A methanation catalyst for the methanation of carbon monoxide and/or carbon dioxide is disclosed that provides high selectivity and stability, and additionally shows improved activity compared with prior catalysts. The methanation catalyst for the methanation of carbon monoxide and/or carbon dioxide comprises aluminum oxide, a Ni active mass, and Mn, wherein the Ni/Mn molar ratio in the catalyst is 3.0 to 10.0.

Abstract: The invention relates to a catalyst for the methanation of carbon monoxide and/or carbon dioxide, said catalyst comprising aluminium oxide, an Ni-active substance and Mn and being characterised in that the molar Ni/Mn ratio in the catalyst is 3.0 to 10.0, preferably 4.0 to 9.0 and especially preferably 5.5 to 6.5. The catalyst is characterised by an increased activity with high selectivity and stability. The invention also relates to a method for producing a catalyst according to the invention, comprising the steps: a) co-precipitation from a solution containing Al, Ni and Mn in dissolved form in order to obtain a precipitate; b) isolation of the precipitate from step a); c) drying the isolated precipitate from step b); and d) calcination of the dried precipitate from step c).
