CO2 recovered from industrial flue gas can be hydrogenated using H2 produced from H2O using renewable energy, for manufacturing chemicals (lower olefins such as ethylene and propylene, methanol, and carbonates), and fuels (such as liquid transportation fuels including gasoline, diesel and jet fuels, methanol/DME, or synthetic natural gas). The challenges are to develop highly selective and active catalysts and energy-efficient catalytic processing, apart from the need to lower the cost of H2 production using renewable energy. This presentation will discuss some new bimetallic catalysts (M1-M2, M1=Fe, Pd, Co, M2=Co, Cu, Ni, Pd) based on our recent research at Penn State and based on our collaboration with researchers in China, Thailand, and Japan. The hydrogenation of CO2 over novel bimetallic catalysts can selectively produce either C2-C4= olefins(and C5+ liquid hydrocarbons) using Fe-Co catalysts, or methanol over Pd-Cu catalysts. Nano-structured catalysts based on hollow zeolite-encapsulated Ni nanoparticles can create a highly stable and carbon-resistant catalystsfor co-conversion of CO2 and CH4 in bio-gas and natural gas to syngas for chemicals and ultra-clean fuels. Some recent advance in industrial CO2 conversion will also be briefly discussed.
