Recently, Dr Yi-Tong Wang (Associate Prof., College of Metallurgy and Energy, North China University of Science and Technology) and Prof. Zhen Fang<\/strong> published an article in Industrial Crops & Products about using highly stable NaFeO2<\/sub>-Fe3<\/sub>O4<\/sub> composite catalyst from blast furnace dust for biodiesel production.<\/p>\n

Highly stable catalysts were prepared by wet impregnation of blast furnace dust (BFD) in Na2<\/sub>CO3<\/sub>\u00b7H2<\/sub>O, Na2<\/sub>CO3<\/sub>\u00b710H2<\/sub>O, NaHCO3<\/sub> and Na2<\/sub>CrO4<\/sub> solution and subsequent calcination of 300-600 o<\/sup>C. At low temperature of 65 o<\/sup>C for 2 h with methanol\/oil molar ratio of 15\/1, high biodiesel yields of 100 wt% were obtained with 7wt% Na2<\/sub>CO3<\/sub>\u00b7H2<\/sub>O@BFD300<\/sub> and Na2<\/sub>CO3<\/sub>\u00b7H2<\/sub>O@BFD400<\/sub> catalyst (impregnating with Na2<\/sub>CO3<\/sub>\u00b7H2<\/sub>O solution and calcining at 300 and 400 o<\/sup>C) added for the first use. Na2<\/sub>CO3<\/sub>\u00b7H2<\/sub>O@BFD300<\/sub> catalyst exhibited outstanding stability and recyclability with biodiesel yields of 100 wt% at the fifth use (93 wt% at the twelfth use) owing to impregnated Na2<\/sub>CO3<\/sub> reacting with Fe2<\/sub>O3<\/sub> in dust to produce stable and active nanocomponents of NaFeO2<\/sub> (32.42 nm) and magnetic nanocomponent of Fe3<\/sub>O4 <\/sub>(size of 3.14 nm and Ms of 6.16 Am2<\/sup>\/kg) in dust existing. The study provided practical guidance for biodiesel industrial production.<\/p>\n
