Improved Preparation of Cu/Zn?Based Catalysts by Well?Defined Conditions of Co?Precipitation and Aging

In order to enable science- and knowledge-based adaptation of catalyst materials new demands, e.g., methanol synthesis from CO2, a modified method prepare Cu/Zn-based catalysts based on the strict consecutive execution co-precipitation aging is investigated. By successfully stabilizing initial co-precipitate, two mixing regimes are revealed: regarding slow mixing, particle size co-precipitate decreases with increasing volume flow. contrast, no longer influenced by for sufficiently high flows. While can be accelerated forming smaller aggregates in co-precipitation, final state found defined thermodynamic equilibrium alone. Furthermore, microstructure was performance direct dimethyl ether improved adjusting co-precipitation. We believe that approach could scaled-up industrial production rates and, hence, promising make CO2 more effective sustainable.
