Production of biodiesel at low temperature using bifunctional Na-Fe-Ca<\/strong> nanocatalyst from blast furnace waste<\/strong><\/p>\n

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 Fuel about using highly active bifunctional Na-Fe-Ca nanocatalyst from blast furnace dust for biodiesel production.<\/p>\n

Nanocatalysts for biodiesel production were prepared via wet impregnation of blast furnace dust (BFD) in Na2<\/sub>CO3<\/sub> (Na-BFD) and CaCO3<\/sub> (Ca-BFD) suspension solutions and calcination at 500 and 600 o<\/sup>C, respectively. Biodiesel yields of 100.0 wt% (Na-BFD500<\/sub>) and 98.3 wt% (Ca-BFD600<\/sub>) were achieved at 65 o<\/sup>C. Synthesized catalysts showed outstanding activity and recyclability, due to the transition of CaCO3<\/sub>, Na2<\/sub>CO3<\/sub> and Fe2<\/sub>O3 <\/sub>to nanocrystals of NaFeO2<\/sub> (29.9 nm), Ca2<\/sub>Fe2<\/sub>O5<\/sub> (10.5 nm), CaO (100.1 nm) and Ca2<\/sub>Fe2<\/sub>O5<\/sub> (50.0 nm). Na-BFD500<\/sub> achieved 95.8 wt% biodiesel yield with 16 cycles, whereas Ca-BFD600<\/sub> reached 94.1 wt% biodiesel yield with 7 cycles via magnetic separation. BFD containing convertible magnetic and active components (Fe2<\/sub>O3<\/sub> and CaCO3<\/sub>) was an ideal raw material to synthesize catalyst for biodiesel production with high catalytic efficiency and easy separation. The study provided a practical utilization of industrial solid waste for biodiesel production.<\/p>\n
