Synthesis of Light Olefins from CO₂Hydrogenation on Fe/ZSM-5 Catalyst

Abstract:

A Fe/ZSM-5 catalyst was prepared by impregnation method and evaluated in the synthesis of light olefins from CO₂ hydrogenation. It is found that The conversion of CO₂, the yield of light olefins and hydrocarbons content reach 82.42%, 12.65%, 0.4885mol respectively under the conditions as follow, mass concentration of ferric nitrate 9%, silica to alumina ratio 25, calcination temperature of the catalyst 500°C. By the studies of NH₃temperature programmed desorption, performance changes of the catalysts was analysis. A possible mechanism is proposed on the basis of mineral composition changes of Fe/ZSM-5 catalyst in the synthesis of light olefins through XRD analysis.
