1. A process for producing a tableted shaped catalyst body, which comprises the steps of:

  • (a) combining of (i) at least one aqueous solution of copper compounds, aluminum compounds and optionally transition metal compounds and (ii) at least one aqueous carbonate-containing solution to form a precipitate, isolation of the precipitate, optionally washing of the isolated precipitate and drying of the isolated precipitate to give a dried precipitate, and(b) tableting of the dried precipitate obtained in step (a), wherein step (b) comprises;

    (b1) calcination of dried precipitate obtained in step (a) at a temperature in the range from 250 to 900°

    C., to give a calcined precipitate,(b2) mixing of dried precipitate obtained in step (a) with calcined precipitate obtained in step (b1) in a weight ratio of dried precipitate to calcined precipitate in the range from 2;

    98 to 98;

    2, to give a mixture, and(b3) tableting of the mixture obtained in step (b2).
