South Korea successfully develops new iron zirconium catalyst
Recently, the South Korean research team has developed a new and efficient metal catalyst that can convert synthetic natural gas (Syngas) into clean fuel.
The Korea Research Consortium recently published, Professor Pei Zongyu of Sung Kyun Kwan University (transliteration) team developed an iron zirconium metal catalyst, the liquid fuel hydrocarbons clean conversion of synthesis gas generated in the ironmaking process for.
Synthetic natural gas contains a large amount of carbon dioxide and carbon monoxide, which can be synthesized by Fischer Tropsch (Fischer-Tropsch) synthesis. Up to now, the iron catalyst is the main catalyst to improve the efficiency of this kind of reaction, but the sintering of iron (small particles, coagulation, large particles) will slow down the reaction rate.
The team mixes iron with zirconium metal oxides, thus delaying the sintering of iron. Generally speaking, the iron catalyst from the reaction will slowly reduce the initial reactivity in the hole formed in the iron oxide 6~7nm (2~50nm on the surface of metal oxide medium porosity) ZrO2 lattice structure, can improve the thermal stability of the Fischer Tropsch reaction, this new type of catalyst can ensure smooth reaction in 60 hours.
Prof Pei said the research could easily convert greenhouse gases such as carbon monoxide and carbon dioxide into liquid fuels, which would replace gasoline and diesel, as a new source of power. Therefore, the significance of this technology is significant.
On the other hand, the study was supported by the Korean Ministry of science and technology communications, the Korean research consortium C1 gas refining business, the Korean Ministry of education, the Korean research consortium, basic research services, and other aspects.
