Recently, Dr Yi-Tong Wang (Associate Prof., College of Metallurgy and Energy, North China University of Science and Technology) and Prof. Zhen Fang published an article in Journal of Cleaner Production about electric furnace dust impregnated with Na2<\/sub>CO3<\/sub> solution for biodiesel production.<\/p>\n

Solid catalyst (Na2<\/sub>CO3<\/sub>@EFD) was prepared by wet impregnation of electric furnace dust (EFD) in aqueous Na2<\/sub>CO3<\/sub> solution. It had high basicity and acidity of 0.34 and 0.16 mmol\/g for biodiesel production. High biodiesel yield of 99.8 wt% from soybean oil was obtained under the optimized reaction conditions (by Central Composite Design) of 71 o<\/sup>C in 111.36 min with 5.4 wt% catalyst and methanol\/oil molar ratio of 11.8\/1. After 11 cycles, biodiesel yield still maintained at 90.8 wt% with catalyst recovery rate > 90 wt% by magnetic separation of catalyst EFD powders (containing Fe3<\/sub>O4<\/sub> with magnetism of 59.1 Am2<\/sup>\/kg). Pure Na2<\/sub>CO3<\/sub> particles presented poorer recyclability with lower biodiesel yield of 89.5 wt% even at the eighth cycle by centrifugal separation. Na2<\/sub>CO3<\/sub>@EFD catalyst had high activity and recyclability because: (i) EFD as support hosted nanoparticles of Na2<\/sub>CO3<\/sub> (30.3 nm) as main base site for transesterification; (ii) porous EFD support provided acidic sites from metal oxides (e.g., ZnO and Al2<\/sub>O3<\/sub>) for esterification; (iii) EFD adsorbed active components into its micropores to maintain high recyclability; and (iv) EFD magnetism from magnetic Fe3<\/sub>O4<\/sub> kept high efficient magnetic separation. Total metals in the blended biodiesel met the National Standard of China and heavy metals were lower than typical petrochemical diesel. The study provided a practical use of industrial solid waste for the green production of biodiesel.<\/p>\n
