Description
Summary:New active and selective catalyst compositions for the hydrogenation of CO2 to mainly fuel‐type higher hydrocarbons were developed by application of an evolutionary strategy. It was shown that Fe and K supported on TiO2 and modified by Cu plus other modifiers resulted in highest selectivity for C5–C15 hydrocarbons at high degrees of CO2 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 CO2 conversion with still low selectivities to methane at higher reaction temperatures and a higher H2/CO2 ratio. Fuel for thought: New active and selective catalyst compositions for hydrogenation of CO2 to mainly fuel‐type higher hydrocarbons were developed by application of an evolutionary strategy. A detailed study of the reaction conditions revealed that modified Fe catalysts supported on TiO2 resulted in high selectivities even at high CO2 conversions.
