Light olefins can be produced by petroleum processing, direct/indirect conversion of synthesis gas (CO + H<sub>2</sub>) and hydrogenation of CO<sub>2</sub>. Among these methods, catalytic hydrogenation of CO<sub>2</sub> is the most recently studied because it could contribute to alleviating CO<sub>2</sub> emissions into the atmosphere.
