on oxygenate selectivity in Fischer-Tropsch synthesis on iron alloy catalysts in ACS Catalysis
Fischer-Tropsch synthesis is the conversion of synthesis gas, CO+H2, into liquid hydrocarbon fuels, and is eminently suited for producing clean synthetic fuels by using renewable electricity for electrolysis of CO2 and water to generate syngas. In this way, green energy can effectively be stored in liquids of high energy density, which also allow utilization of the existing infrastructure for the fuels we use nowadays. Besides the possibility to make clean fuels, there is also a need for producing chemicals, for example alcohols such as ethanol, propanol, and aldehydes, which are important base chemicals for the industry. In standard Fischer-Tropsch synthesis with iron catalysts, roughly 8-10% of the converted CO molecules end up as oxygenated hydrocarbons, of which about 60-65% are alcohols.
