New active and selective catalyst compositions for the hydrogenation of CO 2 to mainly fuel‐type higher hydrocarbons were developed by application of an evolutionary strategy. It was shown that Fe and K supported on TiO 2 and modified by Cu plus other modifiers resulted in highest selectivity for C 5 –C 15 hydrocarbons at high degrees of CO 2 conversion. Co containing catalysts were less suited since they produced methane and light hydrocarbons with high selectivities. A detailed study of reaction conditions showed that selected catalyst compositions were able to reach high CO 2 conversion with still low selectivities to methane at higher reaction temperatures and a higher H 2 /CO 2 ratio.
