Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>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.</p> </abstract>
