Within the scope of this thesis, ternary Cu/ZnO/Al2O3 catalysts were prepared in novel, continuously operated micro process engineering setups with micromixers applying sodium, ammonium and potassium carbonate as well as sodium hydroxide as precipitation agents. Performing the precipitation in slit plate mixer and valve assisted mixer results in catalysts with equivalent or even preferred properties compared to the conventional batch process. Especially the composition of crystal phases, the specific copper surface area and the catalytic activity in methanol synthesis of the catalysts prepared in micromixers displayed industrially relevant capabilities. The novel synthesis routes for the precipitation of catalysts for methanol synthesis possess the potential to replace the conventional synthesis in batch reactors by continuously operated precipitation.
