Recent developments in the conversion of synthesis gas to short-chain alcohols over Cu-Co-based catalysts
Cu-Co-based catalysts provide promising systems for higher alcohol synthesis (HAS) due to a synergistic dual-site mechanism. Bimetallic Cu-Co (alloy) nanoparticles are assumed to be the active sites, but cobalt carbide (Co2C) forming under reaction conditions also seems to influence the formation of C2+OH. Na-doped Co-modified Cu/ZnO/Al2O3 is applied asb enchmark catalyst within the Carbon2Chem subproject L4 providing suitable performance in terms of CO conversion and C2+OH selectivity. However, further optimization is required in order to develop an economically viable HAS process.
