Abstract

Development and evaluation of novel catalysts capable of activating CO₂ especially in CO₂ hydrogenation have been investigated. Several catalysts have been prepared, and characterized by CO₂ TPD. Their performance has been evaluated at 300 °C and 10 bar. All catalysts were active in CO₂ hydrogenation reaction with conversions of approximately 15–30% at 24 h time on stream. Potassium was found to enhance chain growth and to decrease the formation of methane. Ru promoter did not provide any benefit in activity or selectivity. Zr-promoted catalyst materials exhibited enhanced CO₂ adsorption and improved hydrocarbon yields.
