Abstract

The synthesis of liquid hydrocarbons from CO2 and H2, based on renewable energy and H2O electrolysis, respectively, in a power-to-liquid process is a promising concept for the substitution of fossil fuels. Such a process is based on Fischer-Tropsch synthesis followed by hydrocracking to convert waxy products into transportation fuels such as gasoline and diesel oil. Heteropolyacid cesium salts as catalysts show appropriate activity for hydrocracking, and the selectivity in cracking model hydrocarbons and Fischer-Tropsch wax can be tuned by the vanadium content of the catalyst. Thermal stability and surface properties were investigated, and the catalysts are compared with a classical H-Y-type zeolite used for hydrocracking.
