Abstract：Growing emission of CO2 has brought a range of negative effects on the environment. At the same time, petroleum resources are becoming increasingly scarce, and the industrial development of LPG (propane and butane) production from petroleum is facing serious challenges. The production of LPG by reacting hydrogen from renewable energy sources with CO2 presents a way to mitigate environmental problems and replace finite petroleum supplies. Compared with the direct pathway mediated by CO intermediates, the hydrogenation of CO2 to LPG with methanol as an intermediate product bypasses the traditional Fischer-Tropsch synthesis reaction and enables for efficient conversion of CO2 . Currently, there is significant interest in coupling the CO2 hydrogenation to methanol process with the methanol dehydration to hydrocarbons utilizing bifunctional catalysts with metal oxide and zeolite. The main difficulty in CO2 hydrogenation to LPG via methanol is to develop catalysts with high activity, selectivity and stability. Herein, based on the thermodynamic analysis of CO2 hydrogenation reaction, the catalysts for CO2 hydrogenation to LPG via methanol were reviewed, including the catalysts for CO2 hydrogenation to methanol, the catalysts for methanol to low carbon hydrocarbons, and the bifunctional catalysts with metal oxide and zeolite. Additionally, the future development directions of catalysts for CO2 hydrogenation to LPG via methanol were prospected.
