ABSTRACT:
The invention relates to a process for preparing Cu/Zn/Al catalysts. In this process, the metals are used in the form of their formates and are precipitated in a suitable form. Suitable precipitants are, for example, alkali metal carbonates. The invention further relates to a catalyst as can be obtained by the process according to the invention and to its use.
