Title: IRON-DOPED NICKEL METHANATION CATALYSTS
Abstract:
The invention relates to a catalyst for the methanation of carbon monoxide and/or carbon dioxide, comprising aluminum oxide, an Ni active mass and Fe, characterized in that the molar Ni/Fe ratio in the catalyst is 4.0 to 25.0, preferably 5.0 to 10.0, and particularly preferably 6.5 to 7.5. The invention also relates to a method for producing a catalyst according to the invention, comprising the following steps: a) co-precipitation from a solution containing Al, Ni and Fe in a dissolved form in order to obtain a precipitate, b) isolating the precipitate of step a), c) drying the isolated precipitate of step b), and d) calcining the dried precipitate of step c).
