Promoted and bimetallic Cu-based catalysts for synthesis gas conversion

Ethanol and higher alcohols are promising fuels/fuel additives and chemical building blocks. Bioethanol is commercially produced via fermentation of sugars, but can alternatively be synthesized via biomass-derived synthesis gas (CO/H2) [1]. Alkali-promoted CuCo bimetallics and Mn-promoted Cu-based catalysts show promising results towards higher oxygenates, but lack of sufficient particle size control and reproducibility [2].

The focus of this study is to find reproducible and particle size-controlled, Cu-based catalysts towards a selective, active, and stable production of higher oxygenates via CO hydrogenation. Promoter and bimetallic effects are studied by using different surface-tuned, carbon-based supports [3]. pH-controlled incipient wetness impregnation and colloidal approaches will be explored to synthesize the catalysts. Catalytic activity and long-term stability tests will be investigated in high-pressure and high-temperature parallel reactors.
