The foundation to produce clean fuel and petrochemical products using carbon dioxide has been prepared. Prof. Jongwook BAE and his research team claimed that they have developed a generic technology to produce a petrochemical intermediate from carbon dioxide using a catalyst.
The need for a technology that efficiently removes carbon dioxide has increased due to the exhaustion of oil resources andglobal warming. There has been a research on catalyst technology that synthesize petrochemical materials with the use of different intermediates suchas methanol and dimethyl ether. However, it remained incomplete as they couldn’t solve the issue of efficiency decreasing after the deactivation of the catalyst.
The research team was able to induce synthesis of dimethyl ether from the carbon dioxide by developing a catalyst synthesized with alumina and nanostructured copper. The alumina that has been inlaid with 5~8nm of patterned pore improved the thermal stability and the catalyst remained stable/efficient even in the condition of high temperature/pressure.(rate of conversion for carbon dioxide improved about 30% as they included oxide from gallium or zinc with the catalyst)
Furthermore, the research team produced a structurally stabilized meso-porous alumina and zeolite to develop a technology synthesizing basic distillate (olefin, benzene, toluene, xylene, etc)

Prof. Jongwook BAE explained, “the productof this research is a high-efficient and stabilized catalyst technology to convert carbon dioxide, which is the main source of the global warming. It will become a generic technology that synthesizes clean energy and petrochemical intermediates.”
This research was done under the support of Ministry of Science and ICT, and National Research Foundation of Korea’s C1 Gas Refinery R&D center. In December 10th, the result of the research was published on the ‘ACS Catalysis’, which is an international scientific journal.
