This is a publication from 2022 outside the Eurokin consortium (and thus not a real Eurokin deliverable). Prof. Matthias Kind has kindly shared with the consortium for information and interest. The work concerns a modified method to prepare Cu/Zn-based catalysts based on the strict consecutive execution of co-precipitation and aging for e.g. methanol synthesis from CO2. By successfully stabilizing the initial co-precipitate, two mixing regimes are revealed. With slow mixing, the particle size of the co-precipitate decreases with increasing volume flow, reaching a constant size at high volume flows. The performance in dimethyl ether synthesis was improved by adjusting the mixing in the co-precipitation. The authors believe that the approach could be scaled-up to industrial production rates.
